We always recommend that you order a sufficient quantity of lollies for your promotional campaign and avoid excess stocks. If you do need to store the products then you have to follow general food storage guidelines in making sure the products are stored in a cool environment, away from sunlight and humidity in much the same way as you would any other sweet or confectionery item. We would suggest storage of no longer than 6-12 months but please check for each individual product as they have different ingredients.
