Can one rely on Paypal IPN solely to record purchases?

Question

I\'m setting up a simple \'buy now\' transaction from a website with these major steps:

1. Select product from price list
2. Review selection (amounts, tax etc)

Answer 1

For a typical e-commerce site, yes you can -- it's fairly reliable. If nuclear reactors will melt down and people will die, then no you can't -- I've seen problems with it, but very infrequently.
