Im only keeping a single campbelli. but notice the prices in LFS's vary a lot by pattern/color. For example, one that has say differnt number of stripes one side to the other will be worth less.
It's the case here in China/HK, last year there were a lot less thai thin bars vs indos, prices were higher for thai thin bars, this year vice versa. thai wide bars still highest cost, especially if bars are even numbered and highest 3 barred. costs increase by multiples with size because they grow so slow.
