I bought a large mug, large t-shirt and a sticker. They took rather a long time to make it to my side of the Atlantic (Cafe Press sent me a feedback questionnaire a week before they arrived! but anticipation is half the fun

.) The T shirt makes me look like a paunchy, prematurely-aged gimp having a bad hair year. This is a big improvement on my normal look, so 8/10 for that!
The mug is gratifyingly large, and lasted three days in the kitchen at work before disappearing by the time I arrived this morning. (If I have a criticism, it'd be that the black on the mug looks a little washed-out - more of a dark muddy-gray than black.) The sticker is wedged into the corner of a spare display on my desk, waiting for a permanent home -- I don't own a laptop of my own (they're technically my employer's), my main machine is already covered in stickers, and anyway is nearing it's 10th anniversary so is expected to go 'ping!' at any moment, and I'm buying a new car shortly which will probably get it. Bumper stickers are rare round here, and someone's going to find themselves staring at it for 30 minutes in a traffic jam on the A48 each day I drive to the office, which should bring in a few hits.
The world is not yet ready for photographic evidence for all this, believe me!
Doug -- the swag is great, & good value for money, but have you considered some sort of direct donation facility? I hear bad things of PayPal, but there are alternatives. I'd certainly be ready to chip in a few bob now and then, I'm sure others would as well. Just threaten to bring in banner ads, and it'd be like the "stoning" scene in "Life of Brian", but with money.
