I'm trying to work out a trade with someone on the opposite coast for a single bottle of Hunaphu. He hasn't specifically said what he wants in return just that he's open to trade for some Alvarado st. cans. My question is, since my shipping cost will be higher than his, should I factor that into how many cans I offer him or do you guys just go by the worth/rarity of the beer itself and not factor in shipping costs? I was thinking of offering 5 cans (about $25 retail + around $30 S&H) for his Hunaphu. Does that seem fair?
