Generally, you tend to get what you pay for, I've found. I tend to aim for the item one price tier above the dead-center price. IE: If I'm buying toothpaste, and tubes are being sold for $2, $3, $5, and $8, I'll buy the $5 one.
Some things are worth shelling out extra for (people have already mentioned cookware) and other things are not (Oh wow, PREMIUM rubber bands!). Generally, you'll want to shell out more for things that last a long time.
