Christ, those are some high conversion rates. Currently I'm at .81%, but with several thousand clicks per day, it works out ok for me. However, would be fantastic to increase that rate!
My sites have been converting very well using the shopping carts (AOM). Obviously this only counts visitors that make it to checkout, so it is somewhat misleading. Ordered items 131 Clicks 323 Conversion 40.56%
nichevalue, how many stores do you run? Any chance you'd be willing to disclose your urls? Oh and congrats!
