If it were me,, and I wanted to sell them I think I would try Craigslist !! Its free and a lot of people watch the listings there !! Even though you are in Wimberley,, you could list them in any major city within driving distance !! But your ad needs to appeal to a certain type buyer so explain well and tell what you know about them !! With spring almost here I could see these in a garden setting !! Give ideas how someone could use them and price them individually !! You might have better luck selling that way. Many people might buy one but not a lot would buy two of them !! You might say X amount for one or a little less for both !! Makes people feel they get a good deal !! Just remember that they will try to get the price down so decide what your bottom dollar is and start above that !!
