Any experience with buying from http://www.adolcebaby.com?

We are planning to purchase a car seat and stroller online, and this site has great prices, free shipping over $50, and a 10% off coupon code (ADB2009).

Having said that, online reviews for this site have been extremely mixed with either very pleased customers or buyers with serious customer service complaints (e.g., orders not being shipped, delays on credits for returns).

Plus, the site has a rating of "F" from the BBB.

I am very leery of buying from A Dolce Baby at this point, but before I completely write them off, I wanted to see what others had experienced with this company.

Thanks!
