Bunch of new retail scam sites all of a sudden
 

Beware:

All scams. Look legit at first blush.

The ".shop" is a red flag on 2 of those. Most legit businesses use ".com". A couple of searches for the ackermah site is really mixed. I couldn't find a legit site, although your link takes you to something that looks real. Getting scammed happens way too much. I sometimes do a search before clicking on links.
