again? 

I'm really confused, I see AP state if you have express satchels you can use them, is that the same with the regular tracking satchels - 500g, 3kg & 5kg? someone mentioned they keep floating around in the system ....surely AP have to honour them?

and looking at the parcel post pdf it looks like over 500g - 22kg is cheaper going fwd??? - could this be true?

sellers is it worth stocking up on satchels?
