Walmart Canada is to discount more than 10,000 products in stores nationwide. The strategy is designed to build market share before expansion and the market entry next year of rival retailer Target.

The offers will extend through July and include price reductions on about 3,000 grocery items.

Recently, Walmart Canada has been upgrading many of its stores to Supercenters. It aims to complete 73 projects by January 2013, including new openings and expansion, refurbishment and relocation of existing stores.
