Whats a reasonable length of time to wait for a delivery from the US to the UK on airmail,I ordered from a well known company in the dealers section on 8th April,it was sent by airmail 13th April,have since received a second order sent with UPS in 4 days,they claim the first order can,t be lost as its "sign for release"and they have never lost one in 3 years,but its paid for and i,m getting kinda jittery,can I say that they have always replied to e-mail in a prompt and courteous manner and I have no complaints about my dealings with them,is this length of time normal,how long do I wait and what is my next step,iv,e contacted all local post offices with no luck.
