Amazon Prime is brutal to compete against. I'm averaging around 100 orders from Amazon a year (based on their order stats for my account), and almost whenever I do a search, I tick the Prime search restriction. I know it often means I pay more, but 90% of my purchases are impulsive purchases of the "I want this yesterday" kind where Amazon is competing against brick and mortar stores by me not having to go to a shop, and knowing I'll still have it the following day, and where other online sources don't enter into the picture at all.
The exceptions, where I don't go straight to Amazon, are very specific, and are a handful of vendors that ship as quickly as Amazon and that I go to for specific ranges of products (e.g. my supplements).
The only times I'll comparison shop, and where Prime doesn't come into it at all, is for really big items. E.g. my TV (but the TV before that was from Amazon...). My last laptop (but the two before that were from Amazon).
