It seems like there is a new thread about this every week, so I decided to make a sticky post about it. Generally, the threads go something like this: 1. A developer asks, "Which E-Commerce service should I use?" 2. Someone will reply, "BMT Micro" 3. Then someone else will reply, "Plimus" 4. Then a small discussion about the various pros and cons of each will be discussed, perhaps throwing in names like Regnow and SWREG too. Most developers who post here use Plimus or BMT Micro, and swear by them. Personally, I use BMT, and couldn't be happier- but the same can be said for the people who use Plimus too. Anyway, each service is different, and basically comes down to which service is right for you. There is a very helpful site which displays a nice feature comparison chart, along with pricing: http://www.regshare.com Hope that helps!
