Well, six months after starting Clubcard Plus, we've managed to save just over £85.00, which is after paying the £7.99 p.m. fee, and which I think is worth the effort!
It has changed our shopping habits more than somewhat, in that we choose to stock up on stuff we really know we'll need at some stage, like loo roll, mince and chicken etc., dog food, (or her offal/cheap chicken and veg, which I cook up for her anyway), tins, butter, cheese, bread etc., and of course, we still make sure we only buy wine when the 25% off six bottles coincides with 'a big shop', so we get more savings that way, but as we usually make our own plonk, we just buy the sugar and cider for that! (Economists call all these purchases 'inelastic demand', which is about the only thing I can remember about economics from my college days)!
The sum also includes the usual December splurge, which we didn't actually use, as we both had streaming colds and cancelled the visits, so this month has been pretty sparse, as we have a mountain of cheese to get through and a ton of chicken etc...!
The luxuries we do leave out though, are visits to Andersons Butchers in Cranbrook, (plug plug!), where he does fabulous chops and home-made burgers, and also 'Korkers' sausages, which come from a farm shop nearby, and are the best around as far as Mrs Growster is concerned!
So, all in all, if we can keep doing this, we'll never save the maximum £40.00 a month, but it'll roughly pay for things like the house insurance, so maybe we're lucky to have the time to fiddle around with the buying lists and make the most of it while we can!
