Was a good experience.
Overall Rating -> 9 
I was looking for a small gift for a friend- the process is the same as every other time and was very simple, and she even got her gift early! On the downside, there's no way to easily keep track of multiple Shipping Addresses, so if I want to send a gift to Friend A and to Friend B, I have to overwrite everything and it's a fair bit clunky in that regard.
Overall Rating -> 10
this site is awesome. I was able to look at the products think about purchasing and come back and find the same products. With the amount of inventory gem select has. Its awesome to be able to filter the way that they allow you too.
