Didn't there used to be a section for promotional codes? Can't find it so posting here: Medicanimal.com have a 20% off offer on Feliway at the mo. As an existing customer, two refills to cover the upcoming fireworks just cost me £23.04, which seems to be the best deal around. There's usually a discount on these sites for first time customers so you may get an even greater total discount if you are. The discount also applies to the doggie equivalent.
