Hydrabarriers, sand bag alternatives, 4 - $220 (Menlo park)

I have 3 unused Hydrabarrier alternative sandbags available.
These are large long bags that you lay along a point of entry for flood water, and fill them with water to seal off the area, as you would with sandbags.
These are unused — we ordered extras.
I have three 8ft ones and one 12ft.
I will sell individually $60 for each 8ft, and $80 for the 12, or altogether for $220.
Big storm coming.
Be prepared!
