I used to be sucked into the hype of making a snap decision on something in case it sold out.Now I don't bother & if it's gone --so what? Judging by the number of times items reappear on QVC most will be around for a long time.
Snap, so did I. If something caught my eye I'd watch the presentation to see it properly & get sucked in by the spiel. Now, I research well first, take a deep breath and if I miss out then I play with the dog, have a cup of tea and realise that the best things in life haven't changed because I missed out. And, 9 times out of 10, I can get it another day, in a sale or with a discount code - if I still can't live without it.
