Through the weekend you can take advantage of a couple of sales that are running on T-shirts, posters, calendars, books and whatnot (really, there’s a lot of whatnot) at Retropolis and The Celtic Art Works. And if you just can’t make up your mind, you can combine an order from both sites to make the minimum order.

For T-shirts (at either site, or both) you can get either $10 off a $40 order, or $25 off a $100 order, with the coupon codes PREMIUM$10 and PREMIUM$25. The T-shirt sale continues through February 7.

For the posters, calendars, books and boxes you can get $15 off an order of $50 or more with the coupon code ANN0126. That sale runs through February 9.
