Just get a standard application and take it in.

Dollartree.com/careers
and store address

Go in person and get an application fill it out give it to the manager then you ain't got to worry about all this run around, yeah I've been getting the runarounds too it gives you a job and then it takes you to another one just don't make no sense.

I applied at the store when I worked there. Been 5 yrs or so .
