the opening hours below are right but i never had to be a member to go in there and shop, neither did my mum;. we went to matalan in weymouth and taunton ( UK ) and we were never once asked for memebership details or to fill in anything for a card
I think the opening hours are much the same as all other shops. You do have to be a member to shop there, but they will do it at the checkout for you. Happy shopping.
10am till 8pm generally and you do have to go through the formality of joining takes a few minutes simples
