For example, someone buys my product, then gets redirected to a secure page they can then download their product (but that link won't work if shared with anyone else).
I've heard that PayPal can do something like that, but some on this forum say that it's glitchy with some purchases, and I'd like to avoid anything of the sort.
If there is any free option, great. If not, I can pay the bucks (cheapest would be best, it's not a huge product launch or anything).
I've so far heard of eJunkie & DLGuard, both of which are paid. Any free ones y'all use?
