There is a nice sale on Joules rainboots today. You can still get some use from these this Spring and then have them for messy things in summer like gardening or visits to farms and the dog park.
My children both had Joules boots and they have held up extremely well for us. I just bought a red raincoat from them too and it is really cute.
The shipping should add about $6 but once you order one item, any additional items you may order will ship free!
