What is the marketing strategy behind Subway dropping their foot longs to $5?

Is this an attempt to sink their rivals?

In a word, sort of.

Actually, that’s two words, but I don’t think that Subway is necessarily trying to sink the competition as it is get people into their stores. The REAL money is not made from the subs; the REAL money is made from the chips, cookies, and drinks. Ever price a subway cookie? They charge $1.29 for three cookies that cost them about 10 cents – TOTAL – to make.

And I actually worked in a place that sold fountain drinks. The markup there is at LEAST 100%.
