Stack overflow will send you some stickers if you send them a SASE. Instead of having to get all the stamps and envelopes together, let us do it for you. *
The returned envelope will contain one Stack Overflow, one Super User, and one Server Fault sticker.
*We send an envelope containing a stamped envelope addressed to you as instructed by this company. We cannot guarantee they will follow through and send you the items. Please allow up to 8 weeks before ordering more. If we get multiple complaints of companies not sending products, we will contact them, and remove them from the site until we get an answer.
