Where can I get a Harris Walz sign locally?

I went on the official Kamala campaign web site and they want $20 (which I'm fine with), but $17 shipping. I'm not paying $37 for a sign, especially when I likely wont receive it in time. Any place to get one locally? I went on the Richland County and SC Dem web sites and no mention of them.

Edit: Thanks for the genuine helpful answers. Going to the dem office tomorrow. I legitimately thought this would be a non-controversial post since I was only asking about a sign and not making any statements on candidates or policies, but I guess some people get upset at even hearing other people are voting differently from them.
