Hi Linda,
I like your tips, I would also say use many categories to let your visitors an easy way to browse your store.
anyway in general what do you think about aStores? I think it's only good for big sites with daily return visitors that have a high trust with the site and it's not for every site, I would think that it's better to put a amazon banner with prodcuts then use this, don't know why they don't seems to sale good, as you don't have full control on the code.
anyway I did make a few sales on one of my aStore that got good rank for a little while.
here's some of my aStores
thousands of DVDs: Discount DVDs, New Release DVDs - DVDs
Best DVD Players, Portable DVD Players, DVD Recorder - Best DVD Players
