We are saving some of the spring rains for the garden.  Since putting on the new metal roof it is easier to get cleaner water to save.  So I ordered a recycled barrel from Azure Standard (www.azurestandard.com) for $20 and used a canning jar filler that I already had along with a $20 diverter I ordered from Amazon (https://www.amazon.com/gp/product/B005V3QVRM/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1)for a cheap solution.
