Adult store sponsors that provide an RSS feed
 

...to the webmaster. Any such animal?

Sextoysex.com is probably your best bet if you're after a full catalogue via rss / xml. No code from me, they didn't convert very well, and their owner is a little on the nose.

I use mallcom after trying 3 or 4 different ones over the years. They have a few rss feeds, but maybe not what you're after. Check them out anyway.

PE Cash smells more than old lady wee wee. Avoid.
