+1 on DigiKey - I've bought quite a bit of stuff from them over the years with no problems.

I've also had good luck getting resistors (and other discrete components) from Radio Shack and local electrical supply houses.

My guess is that you:
1) Got part of a bad batch of resistors. Not very common.
2) Are using a meter that isn't very accurate. Very likely if it is a cheap meter or an old one that has deteriorated. A Q&D check of a meter's zero is to touch the leads together - meter should read 0.0 ohms. If you have one of the better meters, you can adjust the zero.
3) You have a high-resistance connection somewhere in the circuit. If you are using crimp connectors, try putting the meter leads directly on the resistor leads. If the reading drops more than a few tenths, try soldering.

Edit: Make sure the meter leads and the points you are measuring are clean. Oxides will raise the total resistance. Some fine sandpaper, steel wool, edge of a knife, etc will knock the oxide and any other crud off.
