If you remember, I made a purchase at an Amazon Store not too long ago. After about a week that the item was shipped out and received, I received a standard email from Amazon Marketplace reminding me to rate my transaction.
I like this idea of an email reminder and hope that eBay would adopt this. An email is sent out on behalf of the Seller to request for feedback from Buyer after a week of closing the transaction. If a feedback for a recent transaction is still not received within three weeks, then an automatic reminder will be sent out.
I find that many people, especially when they are new to online shopping, do not know that they should, though not obligated, to provide feedback and rate the transaction to help the community. Heck, I didn’t even know of such a thing when I concluded my first online shopping! LOL
