Well, it turns out that we in Canada have not been singled out by Frito Lay in the saga of the discontinuation of Tostitos® Baked! Bite Size Triangles that I posted about previously. It appears there are also disappointed fans of this late, great snack food in the US; I did some Googling and turned up a post on another blog (Walt Now Studios) about it.
In fact, a follow-up post on the blog gave me a brief glimmer of hope that they were starting to re-appear on store shelves. Alas, this was not the case: apparently, it was simply a matter of existing stock trickling through the supply chain.
A commenter there did suggest that this was simply a temporary hiatus while Frito Lay harmonizes all their packaging to use the opaque mylar bags; the Tostitos® Baked! Bite Size Triangles should (probably… one hopes, fervently) reappear once the clear plastic packaging is replaced with the new type.
You will hear a great sigh of relief (not to mention the sound of a mylar bag being feverishly ripped open) once they reappear…
