Each year I've had a secret I use to find gifts for people: go to Amazon, find two things I know my gift recipient likes, then compare the "similar items" section to find matches. It's kind of tedious to do, but it works like a charm. This year, I made a GiftMating to do the same things with less effort.<p>Tech behind the scenes: Rails, Zurb Foundation, Amazon Product Advertising API<p>PS: really loving Foundation as an alternative to Bootstrap - you get a responsive layout that you can use by specifying the grid in css instead of in html.
Would be cool if you could give it the URL of a wishlist and it would find the crossovers from that. Would save trying to find two items you think are similar enough to have a useful crossover.
