Yes we sometimes have the odd one get in the wrong pack. We also re-post fences with eco posts, not my favourite job as it’s hard to make a good jobIf I'm doing a new fence I go for the standards but I find I am actually using a lot more eco posts as I am forever life extending conventional wood post fences replacing individual wood with steel. Bit of gloom and despondency when I find I've mixed the 2 up! I spray paint the pointed ends of the ecos when they arrive to try and make it easier to tell them apart
