Poundland are running a special offer in stores at the moment where as long as you spend a minimum of £1 you can get a Disney Beach Towel for £4. They are a pretty big size at 70cm x 140cm and there are several designs to choose from, so at £4 these seem like a bit of a bargain for your holidays. You can choose from an Anna and Elsa Frozen design, an Olaf one, Spiderman or Avengers.
This offer is in stores only, and there is a maximum of three towels each in the terms, so they must be expecting it to be very popular! The offer is on until stocks run out, so that could be tomorrow or in a couple of weeks!
The promotion only started yesterday so you have a good chance of getting hold of some now, but I wouldn't leave it too long as they will go very fast at £4 each.
