Staples price match, part II

This is my second price match(PM) experience with Staples, the first is here. I got a heads-up from RedFladDeals.com that the Microsoft Wireless Desktop 3.0 would be on sale at Futureshop(FS) starting Aug 5 at 39.95, and that Staples have it for 119.95(note: that the price have now been reduced to 79.99). If you do a quick math based on their 150% price match policy, their PM price should be a negative!!!

So I set my phone reminder last night to say "Go to staples!" at 7am (I usually wake up before 8), and I was up and ready this morning. I was checking the futureshop site and the staples site while munching three waffles to make sure that my effort would be a success. At Futureshop site, it's already out of stock online, so I hurriedly check the in-store stock. Lo and behold! all edmonton stores have them on stock! wooohooo!! Watched the clock, and jumped to the car at 7:55 (staples opens at 8am). I think I was the second customer in the store, and after searching for the item, I headed directly to the cashier and uttered the infamous line "I wanna price match it with Futureshop's"

The guy behind the counter would not allow me to PM at first because he said they are a different model. Theirs is comport edition, and futureshop's is desktop 3.0, so I led him to the shelve where their price tag says "Microsoft Wireless Desktop 3.0". And then he's like "Oh, I didn't see that.", then went back to the counter and after a couple of moments uttered "Ok, so they are the same, but I'm sorry I can't do a PM because they are now out of stock at FS. I immediately countered, "yeah! online, but not in stores". So he checked again, and finally gave up, and ask one of the lady to honor the competitor price. =)

Then the cashier lady went gaga as her machine was giving her an error everytime she tried inputting the price match amount of 39.95. She has no idea why, I guess she's not good at math =) After failing to do it for 5 times I think, she asked the other lady and the latter explained that it's because the result is a NEGATIVE! So they did it manually and since the register won't allow zero, my PM price was 1 cent! And as I'm digging in my pocket for a penny, the lady smilingly told me not to bother, lol!!

Then she said "you want your receipt in the bag?". I jokingly said "Oh yeah, so I won't have problem returning the item if I don't like it". She said "oh yeah, so you could get your penny back!"

I'm trying to prevent myself from bursting into laughter the whole time I was in the store.

150% pricematch policy means:
119.95(their price)
- 39.95(competitor's price)
-------------------------------------
80.00
x 50%
-------------------------------------
40.00 (price difference)

39.95 less the price difference equals -0.05!

Imagine getting something worth 120 bucks for free, it's like winning a small time lottery, hehe! If you think I'm kidding, look at this scanned receipt.
