Dear Sir
On 26th November while unpacking boxes of donated items I came upon an envelope containing cash.
I appeal to whoever donated the box along, with the cash, to confirm it was included as a donation in addition to the  goods, or if the money was somehow put in the box by mistake.
Please call in the shop or ring  me on 01325 316 630 so I can acknowledge the gift or return the money.
Honest John
