I’m generally fine with Amazon. The three main things I’d like to see changed:

• Their determined nagging to subscribe to Amazon Prime. I don’t have a good fix there.

• Food. Walmart.com does a better job here IME, uses their existing delivery network to provide perishables in a tight time window.

• Limited product classification for searches. For electronics, Newegg does a better job of having a database with many aspects of products being searchable. In general, specialty rather than general-purpose stores seem to do a better job on this.

If you want an alternative for some reason, OP, you probably want to list what it is that you’d like done differently, as that kinda determines what alternatives make sense.
