I believe it has to be in stock. In other words they are matching the discount so you will buy with them and not L&T. So it must be same size, color, in stock etc
I asked my store and at first they said they couldn't because there isn't a L&T at my mall. Then she called back to say that they could price match what L&T has on their website. I didn't point out that it's OOS there so yay!
