This is just one way to do it. I am sure others have even better systems. Mine is pretty simple and good enough for me: Step 1: start somewhere. I have my best rewards credit card (for me that is Chase Sapphire, but I'm sure a lot of people use Toys R Us Rewards mastercard, Target Red Card, etc) linked to my Raise account. Step 2: Buy discounted gift cards with Raise (I like their app). I buy Target at 10% or above, TRU/BRU at 12% or above, Lego at 5% or above, eBay at 5% or above, and some others. Step 3: Wait for a deal to convert what you purchase on Raise to something even better. For example, what MarxMarvelous did was go on eBay and buy a TRU gift card on eBay for less than face value (this is always a good move, depending on the discount). He used his eBay gift card (acquired previously elsewhere at a discount) to pay for his eBay purchase (the TRU gift card he won at auction). In addition, with the 5x eBay bucks promo (ending in 13 hours) he got another 10% off the price of his TRU gift card in the form of eBay bucks he can used next month. Then he is going to use the TRUTH coupons (look in the TRUTH tactics thread for barcodes) and walk into a TRU on a Thursday (Saturday starting soon) and buy something for a massive aggregate discount after factoring in all of the above. Let's say he got his eBay gift card (to start with) at 18% off. Then another 10% difference between the face value of the TRU card he bought on eBay and the price he won it for at auction. Then another 10% in eBay bucks. Then he is going to use a 20% off one item coupon (see TRUTH tactics thread) at the checkout aisle at TRU, then he is going to get 10% more off if he has a TRU Rewards mastercard and can convince the cashier to let him do a partial pay wherein he puts a little bit on the mastercard and pays for the majority of the purchase with the TRU gift card he won from eBay. AND, what's more he will earn TRU rewards points at 4% for amount not put on TRU mastercard and 8% for amount put on mastercard. When he is done, the price of that $150 Millennium Falcon just got slashed to a total acquisition cost of about $80, give or take. Another thing that you can do is convert one gift card to another. For example, you can commonly buy Target gift cards on Raise for 6% off or better. eBay gift cards run, on average, only 2-3% discount. So I buy a Target gift card and then go to Target.com and use my Target gift card to purchase eBay gift cards, effectively giving me a much better acquisition cost for my eBay gift cards. Which I will then use during an extra eBay bucks promo to buy a discounted Toys R Us (or similar) gift card on the eBay site from some nice lady in Boca Raton. This is a dizzying process, but if you like math, it can get to be a lot of fun.
