I was buying some Christmas cards in Sainsbury's and for some reason remembered how we bought cards in my childhood (1970s). I remember going into Woolworths, where you bought a selection box of 20/40 different cards. Mum would spend ages looking through the boxes, but whichever you chose there would always be a couple of really naff kitten-looking-at-a-bauble cards and that dismal brown-tinted sheep-in-the-snow painting. Everywhere now sells a couple of designs only in a pack. Also whatever happened to:
Paper chain garlands, like a honeycomb that stretched out and you pinned to the ceiling
foil garlands - the expensive version of the paper ones
matt wrapping paper by the sheet, usually with the print a little off-centre on each colour. Up until a few years ago I bought this from the local cheap market, and used it to differentiate Father Christmas presents.
Peanuts and cashews in ring pull cans (usually given as gifts - whoopee! 
)
Christmas tree lights shaped like Victorian lanterns
Christmas may have been tacky back then but it seemed cosier when everything was less "tasteful" :)
