We have the Prime membership and we love it!
The prices compare to the ones we have locally. And it comes in 2 days most of the time. If you order on Thurs or Fri them it takes a little longer.Amazon is becoming one of my favorite sites to shop these days. The prices are considerately lower than many sites. Delivery time is reasonable and the return policies are pretty awesome too. So far I never had any issues even when I had to return some items
