This was my first thought when seeing the cost of printing on the bags. This idea could at the very least be a "plan b" option if you do not reach your target goal. A cool sticker with the logo and site address would be just as good. Possibly better because if you just put them in the welcome bag they can stick it somewhere forever versus tossing the bag in the trash or in a closet.
