No. You can try multiple orders or ordering from different vendors. But, be careful to not go too deep down one path (title). There are opportunities and there are pitfalls. I would not do more than you feel comfortable ordering. For me, I order what I like. If I like it, I might get some more. If not, I don't and usually sell what I have (there's a fan out there for every title - maybe ).
Example: I sold all my Peter Panzerfaust last Christmas sale (didn't have much, but still). I sold almost all my Manhattan Projects.
Thanks for helping me all day today. I was just asking to know. Midtown already closed the Previews orders for East of West last week and I ordered 1 copy because of Hickman (I follow Manhattan Projects).
