Do you guys have websites?
Selfhosted?
Than you might wanna check out
Fotomoto.
You can install a code on your page and every photo will be available for Sale, download, ecard, whatever you choose.
You can set the Layout and the prizes, do promotions, etc.
It's a free service, well, they get provision for selling, but they still have fair prizes.
You still need to promote your website though.
Another option would be opening up an online shop.
Maybe with
zazzle (the link goes to my shop, so you get an idea - I am lagging behind with new products though, most shots are still with from tiny Casio
).
Zazzle is still free, your shop can be as big as you want it to be.
The prizes are not the cheapest, but still alright and in the margin.
There's also
RedBubble (recently sold my first Mounted print *grin*)
Well, it all needs time and work to sell something there - or not.
It depends on your products and the tags you use, clever titles and descriptions help (something most of my older stuff is still lacking *sigh*)
If you have any questions regarding those Sites, let me know.
