You get used to it. The only aspect of it that annoys me is very often the cost of the shipping gets added to the cost of the item so you end up paying a customs charge on the shipping, which seems a little peverse. Either way in the case of something like a helmet kit I usually factor about an extra £50 to the total cost to cover the additional handling, customs charge, and tax.
Is Wasted offering more than one boba jetpack kit? I get confused these days.
