Warmer weather is always better to get visitors out and about and buying stuff. Heaven knows the retail environment needs that.
Greeting cards are those tick over items which can be an important supplement, whatever your product mix. Usually, cards have to fight for retail space, so it is important to stock distinctive designs, like those from Mistletoe House.
If you are already a stockist ( thank you ), make sure that stocks are topped up for the Summer season and if not a stockist, why not give Mistletoe House a go?
