Need opinions on Bridal Party Gifts.

Ok here is what I bought so far:

Bridesmaids:

Small tan tote bag
Day of Jewelry
Lotion and Body Spray from Bath and Body works

Groomsmen:

Engraved Beer Mug
Case of Beer
Day of Socks (I know its weird, but my neighbor suggested it, so all the guys will be wearing the same color socks)


Now I want to get them American Express gift cards to go with it.

Should I get :
$25 for the BMs and GMs and $50 for MOH and BM

OR

$50 for the BMs and GMs and $75 for MOH and BM
