Walmart PM Question

[lisamc]

Has anyone price matched a BOGO at Walmart, now that it's in their policy to do so?  How does it work?  It says the competitor's ad must have a specified price.  But let's say Walmart's price is lower.  Do they raise the price on the one item to give you the 2nd item free?  Or, do you pay the Walmart price on the first item, and then get the second free?  And, if that's the case, why do they need the price in the ad?  

Sorry if I'm missing the obvious here.

Thanks!

For me, in the past they have taken the price in competitor's ad and divided by two, ringing both items at that figure.
