This looks intriguing. A range of 12 well-known beers and/or glasses for £24 with free delivery. On top of that, your first months 'membership' free. The membership is £10 p/m and in the first month you get that to spend on beer. After that, either cancel or crack on! (They also do a 10% off with newsletter sub, but I don't think you could combine these together. If you've tried it, let us know!)
Price per beer: £2 + £10 worth of future freebies.
This deal gets 10 beers, a snack and magazine for £5.95. It is a monthly subscription, which is £29 per month (too much!) so cancel as soon as you've recieved your order. When I called to cancel they offered me the 8 monthly beers for £16 per month, so that offer is available if you want it! Code expires 8th June 2020.
There is quite a lot going on at BrewDog at the moment. Free del on 'Sunshine Bundles'. Chris also found a 10% off code as well for 'new' members. But your mum needs some at her address, so does Phyllis next door.
