Hi - I Purchased last weekend 2 6x6 9ft gate posts which had a few shakes in them. A week later after being stored outside in my garden (covered) now have shakes / splits everywhere. Is this normal? I am not really happy about this as it looks pretty naff.....and do not want to spend the next 20 years peed off. I am due to put them in tomorrow and deciding whether to take them back, if they would take them back. Or will and gate posts do this?
