Purchased a Thunder CC two weeks ago and after shooting it last week I decided to get 3 more magazines.
Eagle is restricting purchases to only one magazine and charges $7 for delivery.
I checked Midway and can order as many as I want from them. Midway's price is a few dollars higher, so I went ahead and ordered three more from Midway and they only charge $4.87 for shipping including insurance for all three.
If I purchased three magazines from Eagle (Bersa) I would have to order one at a time and end up paying a total of $21 for shipping! So I'm not thrilled with Bersa customer service right now.
