I have a website attempting to sell t shirts and other apparel items to nurses. We are using POD like a lot of other small businesses. So anyway, I've had about 4 sales over roughly 3 months to friends and co-workers. But, with over 20k impressions and about 400 clicks I'm starting to feel a little discouraged with PPC ads. Would anyone mind giving me some tips on my site? Price ranges, bad designs, etc?
