If it's not in stock, then make it clear.
If someone orders then make it right.
Brought a Drop Slide from Kulkyne Kampers before easter, online, as the add said they had stock.
Then got an email & a call from them that it was out of stock, They had checked and couldn't get one.
Did I want to wait or a refund?
I took the refund and brough 2nd hand on eBay.
Full marks to Kulkyne Kampers though, they Emailed & Called, and updated the online stock in their shop.
Ordered on Saturday, communication on Monday, refunded on Monday.
ebay on Monday, pickup on Tuesday, installed on Saturday
BTW ebay was approx $300 cheaper so....
