I used to use Wahmcart too, but I dont have it anymore, sold the project I used it for -lol- Definitely not looking to add another monthly subscription since this is just a little one off project.
I do want to go with paypal, I forgot about the redirect. If I name the download page something crazy with a string of numbers and letters and change it every now and then it should make it pretty hard to share. Ill go look at that option tonight.
Thanks for the ideas
