Canadian supermarket operator Loblaw today (16 July) launched a promotion "challenging" consumers to switch from national brands to its own-label President's Choice products.

The company will run a national sale on Presidents Choice products until 7 August under its Switch & Save promotion.

"Now more than ever, in these economic times, Canadians can make the switch from the identified leading national brand products to a President's Choice product confidently, thanks to our satisfaction guarantee," Loblaw said.

If customers aren't "completely satisfied" with their President's Choice purchase, Loblaw has said it will refund the price of the product.
