Re: Plugins required
a thought on the application shop…I’ve experimented lately with hardcoding a pay pal bin button into single.php, and setting up custom fields for the unique info that it needs. that way, you could just use normal posts for the purchasable items. to make things super easy on the sellers, just use the custom field template plugin to give them a very descriptive place to enter the bin button info needed.
for the record, the only reason this method won’t work for my purposes is that I need some sort of inventory control. I don’t see why it couldn’t work for something like software, though.
