Безопасен ли pictureframes.com?

The website is good in the sense that it lets you build custom sized picture frames no matter what size you need your frame to be BUT and this is a HUGE but they charge you a $200 oversize carrier charge if your frame has a 50" combined outside dimension without offering alternatives for other carriers that dont charge that $200 fee. The other thing that bugs me about this site is that when you build a custom picture frame the price of the frame doesnt include acrylic or backing... what am I going to need a frame without acrylic or backing for? you need those things to be able to use the frame but their not included in the price.
