Probably not a good sign when questions aren't answered. I've been burned sending people money for postage and then not getting my item. It's good Listia gives the points back, but hard to get postage returned. I hope this seller is honest.
To make sure you get the most bids and credits from your listings, please add more information about your item. Additional details will help others bid with confidence. This also reduces the number of questions that your bidders have to ask.
Thanks for your cooperation and I hope you earn a ton of credits!
