I have a diabetic cat who is on insulin and I go through one syringe each day. I have one of those yellow 'sharps' containers for depositing the used syringes and when it is full I take it to the vet in exchange for an empty one. I have only had to do this once previously and I was sure I didn't pay anything on that occasion - I simply exchanged the full bin for a new empty one but today I was charged £14.98 for a new bin. I just wondered if anyone on this forum are in a similar situation and pays for new bins every time.
