I can't work out how to get it for less than than £8.49 so woldranger is correct. Good price still at £8.49.
The price is always given excluding delivery and the delivery then advised adjacent. In this case there is more than one delivery option, so what you are suggesting would be incorrect.
Isn't it delivery only from SJS? If so, then it surely should be £8.49 in the title as there's no way to get it for £5.99. If I'm wrong, then let me know how to collect - I'm always up to save a bit of cash.
