I've been looking for a nice jar set for a while. A friend has these and they're pretty good (as far as jars go). After a lot of searching, this is the best price I can find them for. If you're looking for sugar, tea and coffee canisters, I'd recommend these.
+ £3.95 for delivery if you can't pick it up from a local store/have no local store, etc. Which still works out cheaper than everywhere I looked.
Dunelm Mill have a sale on at the moment, so it might be worth checking out their other stuff too.
