I sent a less than full litre of conditioner to someone and it cost $7 to ship! Hardly worth it at all. But thank you for all the good tips.
I thought if you shipped at home from the USPS it had to go priority mail.
Yeah when stuff starts weighing more then a pound it gets expensive. You really can't expect to make back money spent every time, it's more about helping out another curly who really wants it and you getting to clean out stuff that's collecting dust.
