Oh, yep, you’re right! Read the last entry at the bottom, assuming they’d sort by size.You sure? DD is 4 7/8” for $350 (free shipping?) and this shows 4.5-5.5” at $263 shipping included. So it’s either 3/8” smaller or 5/8” bigger for at least $87 cheaper.
Although that’s not WYSIWYG. And that delta with the DD pricing can probably be fully attributed to that. So I think this proves the point the market pricing for a 5” WYSIWYG blue tang is ~$350.
