Did you compile a static list of recommended TVs in different sizes, and just display relevant ones (it looks like it from the markup) or are you actually searching Amazon and pulling back relevant products? (or something in between)
For the MVP I precompiled a list of 3 top selling TVs of all sizes. If it proves to be worth it, I'll add periodic autoupdate for the list and visitor country check, but it still will be prefetched (so yeah, something in between).
