Hot on the heels of the gripes about buying clothes thread, where we are all highly discerning shoppers, what marketing techniques, styling, etc., will you admit to falling for every time?
My weakness is pretentious colour names. If it's blue, orange or pink, then I'm not bothered, but if it's marine, gingerbread or cyclamen then it suddenly seems more alluring. Ditto named garments to a lesser extent (not when they give them random women's names, but interesting, glamorous-sounding ones like Pelerine or Masquerade).
My "never fall for" is the trend of pop-up messages saying things like "Trending item - 18 bought over the past day!" "32 others are looking at this right now!" It's either meaningless (if it's something boring like a mattress protector) or a bit desperate.
