I'm putting a small section on my site that would offer free and low-cost promotional items from my business, to my vistors.
So far I have books and a desktop theme. The section isn't up yet, but I was wondering if someone else had other suggestions? Anything is welcome. If you'd like to view the site to get some ideas, it's at http://www.pawsitronic.com
What about mugs, mousemats and pens? At one of my latest sites, I also plan to offer t-shirts with the logo of the site, the web address and a photo of the village which the site is about on it. I think mugs are a great idea as if you have someone round, and give them that mug then they will probably go visit the site and tell their friends and so on...
The amount I'd be willing to spend would depend on how much interest I could generate in such an idea. Right now I'm just scanning for suggestions. If I got a lot of positive feedback on such a step, then I would definitely go for it!
