Temporary importation while on a trip is different to going on holiday, buying loads of stuff and taking it home. You can't for example buy a MacBook in Nashua, NH [1] when on holiday and bring it back to the UK without declaring it and yet many people do. Lots of advice online to ditch the packaging just in case you get checked.
[1] 0% sales tax in NH. Cross the state line from MA and it is full of shopping malls. Or at least that was the case when I was there more than a decade ago. I never understood what the rules on cross state sales tax were, I think some states require similar declarations and payment.
When I used to spend a lot of time in Memphis, TN we'd drive over the bridge to West Memphis, AK for party booze, it was way cheaper... There were a few big liquor stores at the first exit...
