It all depends on what size the DVD cases are as you can get more slim line ones in B1,B2 0r B4 box,(those

are your best options if sending bulk DVD's and you can print the labels via your printer).

Postage I charge for B1 = $9, B2 $14 and B4 $18,(which covers the price of buying the box and postage cost).

I get 10 slim line ones into a B1 box,28 into a B2 and more than 60 in a B4.

Weights allowed for the boxes and DVD's togetherare: B1 = 1kg,B2 = 3kg and B4 = 5 kg

If they are thicker then you will fit less in them.

Best way to check is buy one of each box and see how many will fit.
