I have enjoyed tremendous success with boxed Christmas cards over the years. The keys are to get in early (immediately after Father’s Day), to promote cards with a charity connection and to display them on trestle tables.
The suppliers I like and which have worked well for me are: Simson Cards (brilliant design range and excellent charity selection), Cardpac (brilliant range and a Peter Mac Hospital connection), Charity Greeting Cards (good charity support) and Hallmark Cards (not so good charity connection last year but much better this year).
I have had no trouble competing with supermarkets and majors as they take a different approach to boxed Christmas cards. They tend to not go out as early. Also, their range is usually more limited.
christmas already geeeeeeeeees time flies when you are having fun , i suppose calenders are already orderd so might as well move into xmass
