When you place an order through my web site, your payment is processed - and your merchandise is shipped - by one of the vendors I use to print the goods you've purchased.
You should receive an email when your order is received; you should get another email when the order has shipped. Those emails will include links you can follow if there's a problem with the order.
T-shirt orders are handled by Spreadshirt. You can find their Customer Service information here. Archival prints orders come from DeviantArt. Their Customer Service pages are here. All my other products - the posters, coffee mugs, cards and so on - are printed and shipped by Zazzle. Their Customer Service section is here.
If you have a question or comment that is not related to an order you can contact me through the form below.
