May not be the case now but used to have donation buttons when you clicked on the individual pages for what you wanted to download
http://www.simfantastic2.com/index.htmThe site is coded in frames so can't link to the actual specific page as I don't know the html name for it but in Downloads, Objects, I clicked on the first item and underneath the "Download Now", there is a button for "Make a Donation".
The site isn't bad though - I noticed there are reviews on the stuff packs which is always nice.
Edit:He does beg for donations on like every friggin' page.. it's kind of embarrassing for him
Sorry, I only just came across that in the stuff packs section
here. Scroll down towards the bottom.
Technically though or from what I read, he isn't offering a "gift" for donating so it isn't classed as a "sale". If he were to say, "I'll give you this if you donate", then it'd ceased to be a donation and become a "sale", from my understanding of it. It seems to be a voluntary donation anyway because you can still download the packs without donating.
Say Red Cross comes knocking and asks you to donate to their cause. You don't get anything in return other than a receipt to say you donated X amount of dollars.
