I don't know if this has been asked before. Too lazy to search the archive. Why don't you sell men's hair accessories in the gift shoppe?
But it might be more dificult to do hair accessories than t shirts.. But maybe someone will drop by with suggestions =)
The gift shoppe is owned and operated by a third-party vendor called Cafe Press. They specialize in offering novelty items (t-shirts, mugs, etc.) with logos customized by people who want to offer their own small line of merchandise without having to front the costs of traditional market research and development of similar products. All you do is supply the logo, select what you want to sell that has your logo printed on it, from their list of items, customize the sale price, and Cafe Press takes care of the rest. Unless they start offering hair care products, you won't find any for sale in the gift shoppe.
I think this is also a good idea. I've spent long hours scouring the internet to find acceptable hair accessories. And wouldn't you know it. I did not find one place dedicated to hair accessories for men. I did not find much in the way of accessories for men. I did not find much in the way of accessories that would work for men. If one site was dedicated to hair accessories for men, they would get the lion's share of the business, I'd think.
