I've been to my local Freeport (Fleetwood) today and they are giving away small potted plants. All they need is either a e-mail address (which is not checked) or a postcode.
They are also giving away M&S voucher booklets with:
20% of casual tops 1st - 31st May
10% off selected bra's 1st - 30th June
10% off menswear on father's day
15% off womens beach and swim wear - 1st - 31st July
FREE xmas multipack cards 1st - 31st August
15% off a £69+ spend on mens and womens suits 1st - 30th Sept
Will be running until stock gone and there was LOADS when I was just there at 4:30pm!!!
