I'm not sure if this offer is available instore as well but I'm pretty sure it is and the local stores are more likely to charge a few extra pennies on top, as they always do but Tesco online are charging £1.99 for 18 packets of Hula Hoops, which is very good value as standard but on top of that, they're also offering BOGOF on this, giving you a fattening, 36 packets of crisps for under £2.
I've already put this in my shopping basket as I can't pass up crisps for 5.5p but lot better not go crazy on this and buy them all before my shopping arrives. lol
Hope this helps....... and if anyone wants the number to get some fat sucked out, consult your local yellow pages. :)
