Just noticed in my local tesco last night that they had all the pound saver range at buy one, get one free. Not sure if it is all stores, but a member of staff said it should be as they try to clear the range.
Products vary, but include:
Picture Hanging Kit £1
Finding Nemo Bubble Bath £?
Pack of 10 highlighters £1
Pack of envelopes £1
And various other bits and pieces. Some useful, some junk! Not sure of the name of the promotion, but was something like pound saver range.
I managed to get some of the small pink food bowls for my daughter.
Anyway - probably not worth a dedicated visit, but worth keeping an eye out next time you are in Tesco! (Instore only)
Hope this helps someone!
