Just thought I'd pop in a quick post as there doesn't seem to have been much activity on this thread lately. Beerwulf continues to offer the best prices of all the main players despite the fact that they have now withdrawn incentives such as a discount voucher if you sign up for the mailing list. Also a few beers on the site such as Delirium Tremens and Westmalle Dubbel are cheaper at Tescos. One tip for a 10% discount per order is to sign up with Quidco and access the Beerwulf site from there.
Lidl seem to have abandoned any form of Belgian beers recently which is a shame and as far as the rest of the supermarkets are concerned it seems to be primarily Leffe Blonde and Duvel. Nice to see Tesco doing the Duvel Tripel Hop which is a great IPA style beer. It would be good to hear if anyone has spotted great Belgian beers anywhere else. In the meantime I'm buying around one case a week from Beerwulf (16 bottles) which, after free next-day delivery and the 10% Quidco discount, costs around £35.00.
