This may seem like a strange question to ask, but i am sure the weed smokers on the board will no why i am asking this, but does anyone know how much a blank DVD case weighs? And would 2 dutch european postage stamps on a jiffy bag with the dvd case and a 7 gram addition added to it inside the jiffy bag be enough for postage to the uk? I think 2 of there stamps will cover you for up to 50 grams of total weight.

I've found some blank cases online just googling, but the site is in italian.
They range between 65 and 77 grams.

Don't know about costs, i don't think that the risk is worth the gain for some grams...

There really is not to much risk, just make sure u put a different name to yours, plus uk law means you are not actually responsible for what gets posted to you, strange but true, check it out.

My mate did it before, 2 successful deliveries 2 days after posting, 5-6 gms, 2 stamps covered it nice, but he sent a 3rd package with about 7gms and it has been 4 days and still no delivery so he is getting a bit worried he over did it or not enough stamps put on to cover weight, which is what made ask the original question.

On ACD i've read of a guy that had his house checked.
You could ask them about cost, there's a whole topic somewhere.
