Query: BUBBLES DON'T WORK ANYMORE

I had not used my pedicure foot spa for ten times before the bubble system completely broke. The main reason that I brought it in the first place was for the bubbles and now they don't work. I want to return it to the manufacturer but by the time I pay for shippping and gas to get to the actual post office it's probably not worth it. Be warned before you buy this.
