What is a loophole you found out and exploited to the max?

I've been making money off of footwear companies for the past 7 years. Started when I was young and Dicks sporting goods had a special warranty on the (at that time) new reebok zig-techs where if they broke you could return them for enough in store credit to get a new pair of the same shoes plus an extra 10 dollars for your troubles. Ended up buying and returning about 8 pairs before they caught on and the company stopped the warranty because they were "losing money" as the cashier put it. After that I moved onto nike where if you buy their products from a discount retailer like ross or tjmaxx and can't return it to the original place of purchase you can send the product back to nike if it has workmanship flaws. Since nike shoes are made pretty thin nowadays doesn't take much to wear them out, send them back in and they will give you a full refund. Not the price you pay but the price they sell the item for on their website. The most nike credit I've owned at one time was 600 dollars. Don't insure your poorly made products.
