Specific to your industry or similar industry no. But as you suggest - in principle across ecommerce, yes. If your title tags and product descriptions are not unique enough, you will get flagged for duplicate content in Webmaster tools. If you've got a bunch of products with a couple of words or product numbers or colors that make up the difference, you'll most likely get dinged - we have. Will you get a site wide penalty drop in rank, product drop in rank or failure to improve rankings probably depends on how widespread your duplicate content is. You'll want to use rel canonical tags on all your pages. There are other advanced steps to take in terms of identifying product landing pages, % exit pages and sales. Index the producers and no-index others etc. I would also look at top ranking competitors and glean what you can from their structural delivery. If they're page 1, they're doing something right. I'd also do a keyword search of this site for duplicate content and you may find other suggestions more specific to your products and industry. Good luck.

The links all point back to your site right? This seems like it wouldn't be an issue with duplicate content since your pages are already established as the original owner of the content. I don't know too much about ShopTab (maybe Kurt can explain more) but if it's pulling it in from an iFrame it may not be an issue at all. Either way, I wouldn't worry too much about this being duplicate content. If you are worried though, you could start by adding just one subset of products first, see how that goes, then add the rest. If you have an example page to look at it I'm happy to check it out for you as well. Thanks! Jen
