ALARM clocks and door knockers are falling out of fashion as households increasingly go high-tech.
In the four months after the final episode of nature series Blue Planet II sales of reusable coffee cups, travel cups and flasks were up 71 per cent on last year.
Love Island spurred a rush in sales of inflatables and water bottles similar to those featured in the show.
However, the "biggest surprise" was a resurgence in the popularity of the thong after years of declining sales. They rose 72 per cent alongside suspenders, which were up 132 per cent.
