Current Scratch Item Availability to the Market

Been looking up a few items of the current Scratch Campaigns and haven't found any on the market. How long does it usually take before folks tend to start selling them on the market? Understandable there is a supply/demand aspect to it all, just that being new I have no experience on what the speed/rate it all ends up going down.

Only AC items can be sold, not SG. AC items are typically listed within an hour or so of the scratch coming out?

Thanks for the info... it's hard to acknowledge what you don't know, am I right? 😉
