There's a great range of goods available here, and all for very cheap. I tend to buy all my gift wrapping, stationery and arts and crafts supplies at Dollar Xtra, but their plastic and home wares are excellent as well.
The Dollar Xtra store is huge! They have such a large selection of products, everything from homewares to cosmetics to artwork and stationery, and everything is very reasonably priced. Their staff are also friendly, too.
