Congratulations! First, log into your Member's Area, click on SELLING, scroll down to SOLD ITEMS, and click on VIEW CONTACT DETAILS, your buyer's contact information will be there.
It is advisable to make contact with your buyer to verify details, such as amount of items ordered, colour, size or other variables. It is possible that two items were clicked when only one was wanted, and it is better to find out now, than after invoicing, in case of minor computer or system problems.
VintageAuctionGalleries.com has a wonderful Invoicing facility where you may apply any offered discounts for single or multiple items.
Please leave appropriate feedback for your buyer.
