As it was mentioned before eBay will have Target gift cards on sale on Thanksgiving $200 for $185, a savings of 8%. Unfortunately there are no details on a per-household limit or how many are available total. But, it is the first item shown on their Thanksgiving ad, so I think we all know it will be a hot-ticket item.
Theoretically (and this is bonkers mind you) you could buy an ebay gift card on the Target with your Red Card...or at Kroger, etc to get fuel points....then use the ebay card to buy the Target card, then turn around and use the Target card to buy Disney cards. Theoretically.
Let's say $200. So, you buy 200 ebay at Target= 190 You use $185 of that to buy a Target card, leaving a remainder of $15. Then, you buy 2 $100 Disney Cards using that $200 Target card, but plug in the Red Card discount. It will take $190 off the card, and leave a remainder of $10. 190-15-10= $165. That's a savings of about 17.5% Not shabby.
Now, I am assuming you can use an eBay card to purchase other gift cards, but I don't KNOW that. And, it is probably a little too risky to spend $3K on eBay gift cards without knowing how many Target cards will be available and the limits. Too rich for my blood definitely. But, even with taking the eBay gift cards out of the equation, that is still a nice little savings. And, you may buy eBay cards, but only enough that you feel comfortable using them at some point.
