Hey there, Oxdarock here!
Before anyone asks, no, this isn't about me drawing requests. Anyway, moving on...
Regarding the last few Patreon Shop posts I've made, they aren't "new", but rather old pictures from my website store that someone asked if they could buy individually. They've been doing decently, more or less, so I figured it's ok to start adding to the store on request.
So, let's open the floor with these! It's simple: if it's from my store and/or has a preview post, you can request it to be added to the shop. Requests need to be made in sets of two and can be paired together regardless of what image series they're a part of (i.e. Snapzine or Patron Picks). However, for quality reasons, any picture from sets prior to Snapzine #5 can only be grouped with other pictures from around that time and in sets of three. Likewise, if it's something I've posted a complete version of publicly, but hide extra versions behind a paywall, they too, must also be suggested in sets of three.
Furthermore, I will not accept individual comic pages as requests, nor will I add anything that's already in the store. You can check out what's in the store at a glance via this DA Gallery (I've updated the "Patreon Shop" link in each of them). And lastly, I will not add anything to the store unless the one making the request intends to make a purchase once it goes up (so no random suggests on what you think people would like). If no purchase is made within 24 hours upon adding it to the shop, I'll remove it out of spite for wasting my time.
Anyway, that's the gist of things. If you're interested or have any questions, please leave a comment below or send me a private message.
