The last time I went to a RadioShack, I was looking for a resistor. I checked their website, which said my local store had it in stock. When I got there, I found the electronic components stuffed in a dark corner and the smaller components were all mixed up in the wrong drawers. After a few minutes of searching, I didn't find the resistor I needed, so I asked the only employee in the store where it might be. She told me that if it wasn't in the drawer, they don't have it. I said "But your website says it's in stock," to which she replied "Oh we never update that."
I always call the store to confirm if the website is correct. And half the time, they don't have in stock what the website claims. That may be why the employees are so eager and helpful in looking for the part.
