If you order enough and you have a decent ISP, it is a good deal but.................................................
The few items I order during the year, I can wait for them to arrive. I had a trial of prime and ordered a couple of 5-gal buckets of solvent which I really wanted quick. I finally got it about 10 days later after contacting them. The first batch (2 day shipping) got lost somewhere. Another time it wasn't something that I needed that quick, but it did arrive in a timely manner.
The movie end of it doesn't work when your ISP is powered by smoke signals. I tried netflix and that was hit and miss also.
Now I need a deal on a fast ISP. Ha!
