question

But this design is on selling, if I take I down (delete) it would be lost rank and "link" for my customer, I just want to send you guys an update the same of my design with a high resolution (300ppi). Can I do that? or if you guy print it with bad quality, just email me & I will send an update design 300ppi for you to make sure the best t-shirt for Merch's customer. Thank you very much.

We really appreciate the ability to delete designs and open up a tier slot. That's a terrific improvement. I hope Amazon Customer's issue is also dealt with in January. When we wish to improve an existing design, we should be able to upload a new file and just have it override the existing png file without having to delete the entire t-shirt, losing sales rank, reviews, etc. It also invalidates links over the Internet. It works for Createspace. Hardly any author or publisher uploads a perfect book file the first time. Some have to upload ten or more times before they get it right. Anyway, that's not a complaint, because we've agreed to give the Merch staff the Christmas present of not complaining. So, for now it's just to put this onto the 2016 agenda. Until then, thanks
