Problems With Us Customs?

[🪦 DVS ●]

I'm from the uk so most of the stuff i want are always overseas :verymad: i've had this happen many times. Some ive picked up and 2 to 3 weeks later receive a bill from customs saying i owe additional charges. How bad is that i already have my item and i still have to pay more money!!!! How ever mad it makes me i still would never rule out never buying from overseas again for 1 its not the sellers fault its our countries and all the terrorism and 2 i would be missing out on some very cool stuff
