Avon are doing 3 for £10 on a whole range of sun care, including the SPF 20 which is £12 on its own! You can also have 2 for £8 across the same range.
Delivery is £3.50 but i went through Google and got a code for free delivery over £20, the code is KWG.
Offer on until August 26th.
I thought this was a good deal, especially as sun cream etc is so expensive in the shops.
Ive put online but may also be available through your avon rep if you have one.
