I'd like to get her some nice microfiber tea towels. They're way better than the cotton sort at drying glass and everything else. I had a look in Spotlight but their towels are too thick. Aldi had what I wanted but I took those for myself (this was months ago). The thing with Aldi is that they circulate their products so something that is there one week, will never be seen again.
I might have a look in Red Dot which is similar to your Dollar Tree.
