Walmart us the best stocked place for "comments needed" things like this and the price is very hard to beat.
They have both low and high quality stuff for great prices and also may have hose fittings and plain hose.
Amazon is best for mail order as they have just about anything on the planet via their network of sellers and if prime then free shipping on most and depending on location sometimes same day.
Walmart has a cheap hose that is in a very small package which one could consider "emergency hose " takes little space and ca get by if needed in an emergency but maybe not for a lot of uses.
