Could be a nice idea, particularly as 2nd class post is pretty economical for packages which are weighty rather than bulky. We just need to make it gets loaded up with interesting items rather than a dozen Palmolive sticks. It could also be a good opportunity for soap makers to get their products circulated around a wider audience.
There could be a rule that a sample is removed from the tub to try the soap instead of everyone just lathering the same puck?
A passaround of soaps would give people a chance to try ones they hadn't.
An idea I've seen before is that a box is loaded with items and sent, any items removed are then replaced with items. It's sort of like a rolling pif that constantly evolves. You could limit it to software?
The rolling PIF idea is great and a quickfire UK-based one would work well. The problem with the one over on the Yankee site was the time delay and the scapegoat that is the international postal system (missing / delayed packages).
Might be a good idea now that shavedash's prices have rocketed... Scoop a sample, put something in and pass on...
Agree with the cheap, easily available soaps (Arko etc..), pointless including them when they are so readily available...
