Somerfield/Coop - Cava/Prosecco & party food - free coupons

I posted this on the groceries thread, but then thought it should be on this one as well , i hope this is ok.

Searched and could not find this - apologies if already posted -
Somerfield/Coop at the moment have vintage Cava and also Prosecco at half price or a bit less at £4.99. also the Coop party food is 1.99 each or 3 for a fiver. Latest Somerfield mag has £3 off £30 spend, plus coupons for £1.00 off party food 3 for a fiver items, and also £1 off the prosecco and cava on offer. So, get 6 bottles wine, just under 30.00, 3 party food, a fiver, get 1.50 or so off for wine discount buying over 6 bottles, 3.00 off over 30.00 spend, 6 x £1 for each bottle cava, and 3 x £1 each item of party food - i think it worked out £21.50ish. Could be SA dependant for the £3 one, but the others dont say cannot combine. Just worked for me anyway - really hope this helps as I never usually find these glitches!
