We give away tote bags with our logo for >$25 purchases. We buy them 150 at a time, so they're fairly affordable. Our customers seem to love them, plus then they're carrying around their yarn (or groceries or whatever) in a bag with our logo on it. The totes have been so popular, people want to buy several, but we can't really justify selling the totes on Etsy since they're not truly a supply, or handmade, or vintage. But the freebie has been really fun.
