Dollar Tree

Everytime I go to this place they always have a sign that they don't have helium. I visit this place at least 3 times a month and one would think that they would get them replaced. Yesterday I went to get some balloons and still they didn't have any, not only me complained of the situation, an older lady also complained that a month ago she came by and still didn't have helium. This needs to change because you'll loose customers for the managers constant careless work.
