mmmm interesting

I use 'plain' BX1 boxes. Main reason I like using these is that they are lighter weight than the AP ones.

I have had no extra charges since I have been using them (6+months) touch wood...

I also use plain parcel bags for my ebay and click and send parcels. They are the same size OR smaller than the AP/ebay ones. Haven't had any issues with that to date.

I don't mind the new AP bags - white and fairly plain unlike the eBay ones.

Hell, I even still put on the DO NOT SAFE DROP stickers.... (for whatever it is worth).
