Whats the best text for selling Viagra? Get, Buy, Order, or Shop?
 

I want to sell viagra and only have a small amount of space on top of a webpage.
I can use:

1. Shop for Viagra
2. Get Viagra
3. Buy Viagra
4. Order Viagra

Which one works best?

I've mostly seen 3.

Why don't you try each one and compare the amount of clicks/sales?

Buy Viagra

I would actually use the word "FREE" in there somewhere since they've all been used and re-used numerous times. Give it a new twist...
