Just managed to get this for £11.70 delivered which seems a really good deal to me.
This was based on me already having 5 items for S&S delivery at 15% off plus another 20% voucher for first order. Some people may only have 10% but it's worth adding smaller value items to bump up the discount.
At the time of posting it applys to:
Robinsons Fruit Creations with Barley, Real Fruit Squash, Low Calorie, Crisp Apple and Elderflower, Pack of 12 x 1 Litre Bottles
Robinsons Fruit Creations with Barley, Real Fruit Squash, Low Calorie, Luscious Strawberry and Kiwi, Pack of 12 x 1 Litre Bottles
Both coming in and out of Stock - more flavours here at the same price: amazon.co.uk/dp/B07BGBKTB2/ref=cm_sw_r_cp_apa_glt_fabc_E26H1DKGS489TVT8P8NF?_encoding=UTF8&psc=1
Hope it helps someone
