School Supplies, Shoes, and Clothes for My Kids

I'm a single mother trying to scrape together any money I can to get my four kids school supplies, shoes, and clothes. They've never had to go without before, I’ve always figured everything out and have made sure they have had everything they have always needed. Its just this is the very first year that I’ve had to do it completely alone with out their dad he paid for everything and I was a stay at home mom for 14 yrs (my oldest sad and whole life) so I mean yeah not trying to get into the whole as to what happened or what was going on but it was not fair to my kids and it was to the point it was not safe for us to be with their dad anymore but anyways (sorry) my children an I would be incredibly grateful for any do any donations to go toward their school stuff
