Do Argos have a price match policy??

Hello guys, does any one know that Argos have a price match policy.

I recently purchased an Epson DX4400 from my local Argos for £29.99 as there were none left in my local ASDA under the £25 promotion.

After I purchased the printer, I noticed on a HUKD thread that people have been able to get it for £25 from comet (under their price match scheme), by showing the news paper advert from ASDA.

Can I go to the local Argos store and claim the difference (£4.99 - I know it's a small amount, but every little helps).

I have the Argos receipt and the ASDA Advert with me.

Thanks!!
