Delta 40X: Leveraging the deal


Last Friday, The Traveler’s Loophole reported “Earn 40 Delta Skymiles per dollar for Pet Supplies ~ Awesome Deal!”   Then, on Monday, Deal’s We Like reported “Deal Alert: Get 40x Delta Miles at PetCareRX!!!”  Yes, I do believe all those exclamation points are warranted.  40X is an amazing deal.  If you need pet food, flea & tick products, etc. you can’t beat a 40 miles per dollar return.  Even if PetCareRX is more expensive than where you would otherwise shop, this could be worth it to you depending on how highly you value Delta SkyMiles.  If you believe the Fair Trading Price of Delta SkyMiles is 1.29 cents each, then 40 miles per dollar can be thought of as a 51.6% rebate!

Buying Miles

Whenever I see a deal like this, I try to look for a way to leverage it to buy miles cheaply.  The idea is to buy items that can be easily resold for as little loss as possible.  In December, for example, I bought and sold cameras from Sears as a way to buy Ultimate Rewards points for .79 cents each.  In February, I bought and sold headphones and watches from Nordstrom in order to buy British Airways Avios (I actually made money on that deal, so the Avios cost me nothing!).  And, in June I bought and sold tablet computers from Sears in order to buy Southwest points for less than .4 cents each (and I earned a Companion Pass!).

For this deal to be worth it, I think the goal should be to buy Delta SkyMiles for about three quarters of a cent each.  If the miles end up costing as much as a penny each that’s still a good deal, whereas if they cost as little as half a cent each you’re golden!  An example may help make this clear:

Suppose you were to buy a $200 flea collar (a really good one!) and sell it for $160 on EBay.  You would earn 8000 miles for your purchase.  EBay fees would cost you about $19, and you would spend, let’s say, $6 more for shipping.  Your cash loss then would come to $65.  In other words, you would have paid $65 for 8000 SkyMiles.  Your cost per mile = $65 / 8000 = .81 cents each.  That’s just slightly above the target I suggested (.79 cents) so I see that as a good return.

Finding Stuff to Sell

This is the hard part!  I try to find items that sell for around the same price as, but prices at PetCareRX appear to be a lot higher.  Read the comments in Deal’s We Like post to see what others have found.  Unfortunately, according to Delta Points, the PetCareRX Deal of the Day items don’t count for SkyMiles.  Rats!  I’m still looking…  As of this writing, I haven’t found anything yet that I’m willing to gamble on.


  • Go through this link to PetCareRX to get the Delta deal.  If you go directly to PetCareRX you won’t get SkyMiles for your purchase.
  • A maximum of 20,000 SkyMiles will be given per order.  That means there is no reason to buy more than $500 worth of stuff in one order.  Note that there is also some confusion about whether you’ll get points for more than one order.  Luckily, Deals We Like captured a screenshot of her Live Chat with PetCareRX in which they confirmed that one could earn more SkyMiles by making more orders.  I’ll still caution you, though, that the rep may have been wrong. 
  • The offer is good “for a limited time”.  I couldn’t find any details at either or PetCareRX that defined the end of “limited time”.
  • Deal of the Day offers at PetCareRX might not qualify.  They appear to qualify, but Deals We Like was told “no” by a rep.  Buy these at your own risk and make sure to take a screen capture that shows the miles you will be awarded.

Paul: Nice job!


I know this deal isn’t around any more, but I wanted to provide feedback on my progress with this deal.

I bought 8 of the k9 Advantix ii for 55+ pound dogs. This was in the top 5 of pet supplies products on Amazon.

I used Fulfillment by Amazon, and sent in the products. Within 12 hours of the items being listed on Amazon, I was sold out. I lost around $160 for 20k miles, so I call it a victory. I am amazed at how quickly everything sold, so my lesson from this is to do your research on what is selling on amazon – their rankings are great!


Guess my comment did not go through earlier — I chatted today and it’s gone…which is a bummer, cause I had $400 worth of pet meds to purchase. :*(


I do not see any offers for PetCareRX anymore


Dima: Yeah, the deal might be dead.

PetCareRX SkyMiles is now offering only 20 miles per $1. Is this 40X deal dead?


I just bought some dog food from there earlier today then stumbled across this. I worked with their chat and the agent happily applied this promotion to my order.

I’m about to buy some meds so I’ll pay the extra $10 and order from there for that too.

[…] can get 40X SkyMiles at […]


I’m debating whether to get in on this or not.
There’s definitely some stuff I could get there for my dog. However, as a pet owner, I’d never buy stuff like flea or heartworm medication off ebay. There’s a pretty big counterfeit market for that stuff, and I’ve heard horror stories about people putting what they thought was frontline on their dogs, but it wasn’t.
So, I personally wouldn’t purchase those products to try to re-sell because they might be hard to re-sell. I’ll see if there’s something else I want to get.

Done this game a year ago and netted 100k miles, which has since become unprofitable. You’ll be lucky to net a 40% margin after eBay fees. Do it at your own risk.


@thesocalledfan. I also bought 3 items from the deal of the day and took a screen shot of the promised miles. I’m going to resell them as soon as i get them. I, however, was cautious and only spent $65. if the miles don’t post and i resell the items, i don’t lose anything.



I am not so sure about the deal of the day caution. (yes, I saw the chat screen shot) I went ahead and bought the deal of the day stuff and it stated I would get 20,000 miles for my purchases. Now, it certainly could bite me later if the deal of the day miles don’t post, but I am cautiously optimistic and certainly the type of thing a chat person may not know. (Not is mention not combining with other “discounts.” It says nothing about “promotions.” So, keep your fingers crossed. I figured it was worth the gamble as I am convinced these will sell well for the right price. I’ll send you the screen shots which show I was promised 20,000 miles. I will complain if needed.


I’ve used this deal to, ya know, actually buy dog medications for the last couple years – their prices are uniformly higher, but a little comparison shopping suggests it’s worthwhile.
I did have trouble getting the full mileage once – although that was with a tiered offer based on total spend – it took a couple chats to resolve. but it did work out.


Andrew: Good idea to use this for buying stuff you actually need 🙂

THEsocalledfan: I think you’re right. Thanks for the email. I’ll update the post to be more of a caution than an explicit statement.
