I combine postage.  Excess postage will be refunded.

Pick up is not available.

 A rough postage guide is

1 to 5 single dvds/blurays is as listed. There is no discount because of size and weight.

6 to 8 single dvds/blurays is $15.50, the same price as 5.

9 to 32 single dvds/blurays is $19.90.  

So, postage per single dvds/blurays goes down a lot for multiple purchases.
