Staff will be at the shop in the Royal Star Arcade on 3rd March between 10.30am to 1pm with information for anyone interested in volunteering.
The charity originally opened a pop up shop in the Royal Star Arcade for Christmas 2014. But the store proved so popular with shoppers that when another unit in the centre became available last year Demelza decided to open a permanent shop.
The shop sells a range of donated goods, clothing, homewares and accessories and also organises craft events and clubs.
More volunteers are needed to help run the shop with tasks including pricing, sorting, window displays and serving customers.
Anyone who is unable to attend but is interested in volunteering can ring 01795 845265 or email firstname.lastname@example.org
