My problems with suppliers is if i pay for over night service on shipping i expect overnight service. There's a few places that take your money for the cost of over night and than ship 3 days later, Kinda defeats the purpose.
Being in Canada i expect high shipping costs.Even duty and customs charges. . i'll pay what it costs.. i don't care .. it's a write off when i do my taxes.
my other pet peeve is only offering one shipping choice... i'll buy from who usually gives me the best options.
