Admittedly, it would be nice when merchant moves their store in it's entirety, that the database at their new site would carry old records for update purposes. However, that would only hold true for exclusive items. Often a vendor will have stores in serveral place: here, 3DCommune, PoserPros. And then some things get either sold outright or moved to Daz. It's the responsibility of the vendor, not the venue to keep customer's updated. Vendors whould be keeping their own customer list for products, and when they change venues shuold email all past customers with the change, as well as notifying them of any contact changes, updates to the product, and solutions to new problems. It's called customer service, and vendors who don't do it wind up with fewer sales in the long run. Not the vendor of brokered products, the vendor who made and actually sells the product. I know this places a burden on the vendors, especially small ones, but unless you're going to commit to exclusivly use a venue and promise never to change, it's something you owe your customers as part of the deal (at least for a period of time). Of course, the longer a product is out, the less important this becomes. If there are any problems with a product, they usually come out in the first few purchases and can be updated or more information added to the readme files for subsequent sales. One point though. This isn't like retail clothing purchases. If there's a problem with a piece of clothing you return it to the store for a refund or replacement. You find the problem the first time you wear an item. This is software sales. Problems become apparent and support, not an exchange, is expected. Again, vendors who support their products well get better sales and a loyal customer base. If a vendor can't keep their own database, at least they should make multiple announcements when there are changes and problems on the various sites where they've sold their stuff, along with posting their email changes widely. Whew!
