It looks like the site Retailsims is going to be closing down soon, due to the admins lack of interest, they're going to let the domain lapse.
Some of the stuff there has actually aged pretty well, so I'd get it while you can. What a shame.
Ya, I was always a fan of that site since I love playing businesses. Most, or all , of everything has already been archived. https://simfileshare.net/folder/89774/
also Vegan will hopefully have their backup available again soon https://sims2packrat.tumblr.com/
Failing anything else, I dl'd about 60-70% of the site back in March also if it's ever needed. No pics with mine though.
