harlyman - we haven't had any similar bug reports concerning the product import errors you mention, but we'll gladly investigate the issue. Please send us email at support (at) apsona.com with any sample data you can provide us.

As for the other question about price updates: if you're talking about the editing or "update all" features in ShopAdmin, they are performed via product id, so they will only affect the record(s) you have selected for editing.

Hope this helps.
