My home clubs - 2 AKC and 1 HRC - don't charge for mailing ribbons. Any HT events I have gone to have been happy to mail them free of charge and I have recieved many that way - whether I left early to get home due to a long drive or just wasn't around at the time of award. Only one (Field Trial) club has asked me to pay for the cost of mailing when I was sick and left early after running my dog in the 4th series. I am likely to not frequent that clubs events again, just saying.
penny pinching regards
