Mine has $1 and $3 items as well. You have to make sure you double check the shelf tag under the bin because they are not organized by price. And also be careful that no one put something back into the wrong bin.
It can be a small issue for me just because I take my grandson to dinner on Wednesdays. Then we usually go to Target since I am not in that area at any other time. My stepdaughter comes with us usually. We've been doing this since he was two, he's now five. And as part of the process of teaching him how to behave in a restaurant we used to reward him with something from the dollar spot. Now we have to make sure we specify a dollar toy!
