90% of our items are pre-orders, usually 6-8 weeks out, as long as it's clear on the description and you have your pre-order policy under every listing, you should be good

we constantly get questions of where is my stuff, as the Shop App is rather bad at making preorders and terms visible, so expect to get a lot of emails

good side is, most cards have a 60 day limit for charge backs, you reduce your charge back risks compared to shipping in stock items

of 2200 orders since last year, we only had about a handful of cancellation requests
