When price goes up

I usually buy bread to bring to work for breakfast. Yesterday I bought a packet of Daily Fresh buns. As I finished the packet I saw from inside the plastic (a transparent part), the price RM1.20 written on it. I had bought it for RM1.40. That's no mystery though, because there is a sticker stuck on top of the original price, giving the new price. (the sticker has the Daily Fresh logo on it, so it's not a rip-off by the seller :P )

Now what this got me wondering is, did they just raise the price? (I very seldom buy this brand) Or did they raise it some time ago, but have so many pre-printed packages that they still haven't finished using them? Hmm...

Okay, dumb post, I know. Just to write something. lol
