BUFFALO, N.Y. -- If you're looking for the best online shopping deals, you don't have to wait until Monday.

That's according to USA TODAY Tech Expert Jeff Graham, who appeared on Daybreak Sunday to give his preview for Cyber Monday.

While he said some great deals will show up Monday, he said many stores have doorbuster-quality sales already up, because they can't afford to wait.

Jeff's advice is -- if you see a good deal on Sunday, go ahead and buy it. If the price goes down on Monday, you may be able to cancel or return the more expensive purchase.
