I spotted this in the Money Saving Expert email this morning and have used it on some cute stocking fillers:
If you go online to costume jewellery brand Buckley London (www.buckleylondon.com) and enter the code MSE10 you can get £10 off when you spend £15 or more across most items until 11.59pm on Tue 13 Nov.
It's valid on both full-price items and already-reduced stock in Buckley's up to 70% off sale, and it can also be combined with other offers such as a 3 for 2 on bracelets (www.buckleylondon.com/bracelets/3-for-2-promotion). However, you won't be able to use the code on Buckley's remembrance poppy brooches, as all charity products are excluded.
