Went into Boots today as I needed a Photo frame. Heart fell when I saw that the one I wanted was in the 3 for 2 promotion with the gift sticker things. Refusing to buy it singly and feel guilty that I'd missed an offer, I then proceeded to spend the next hour searching for 2 more things to buy, before giving up and leaving empty handed.
3 for 2 gifts are just a waste of time and more often than not result in an aborted purchase because many of us aren't organised enough to choose 3 gifts in one trip. Same with online discount codes where the shops expect that most customers will find one. Why can't the price be the price and save us all hassle? Bah!
