Netto's acquisition by Asda is probably common knowledge for most people but for those like me, who drop out of circulation for long periods of time, then it is news.
I have a Netto and an Asda close by and shop at both. I mostly shop at Asda, which is the cheapest supermarket but occasionally go to Netto if there is the odd cheaper item. Currently, I can get tinned tomatoes (until mine have grown in the garden) at 8p per tin cheaper.
When I went to Netto yesterday, I was given a leaflet explaining what was happening. The store will shut for one month and reopen as an Asda store. I can therefore forget about price matching.
I shall be shopping at Netto, one last time, and buying in bulk the various items that are cheaper than Asda. I recommend you do too.
