if your wearing long pants then you should try this.
Pick the good up, like your looking at it. bring out the knife and cut the box open while holding it up. the moment it is out of the box flick it up your sleeve. next put the box back and bend down like your tying your shoes, while doing this slip the goods into your sock.

Note: this takes some skill, practice before you do it. me and my mates used to spend hours practicing. now i can do it without anybody releasing.

if this is to hard just use the double pocket trick i mentioned before.
