Great！But I can not pay with PayPal。。。

Thanks for your reply. I am a Chinese, and I do not have a credit card. So I try paying with PayPal.  But PayPal prompts that the system is temporarily unresponsive. I'm not sure if your account only accepts payments from U.S. PayPal accounts. Forgive my poor English, I hope you can understand what I mean

I already own the following:

Start 10

Multiplicity

Fences

Do I get any kind of Discount on Object 10 because I already spent the $ on these other apps?

Not that it matters but I also own a significant # of Stardock games from Political Machines 2004 to 20016, Gal Civ II and III, Sins of a Solar Empire, Offworld Trading.  I realize those don't really help in the cost of Object 10 but it's mostly to just show that I have been spending $ on your products for a long time.

I followed your link to the upgrade page and entered the info but it is telling me I'm not eligible for the upgrade.  I bought Fences and Start 10 more than a year ago, and I got Multiplicity in Dec. 2017.  All of them were purchased thru Steam, so how am I not eligible?

Steam purchases of individual apps aren't registered into the Stardock store, so it does not see any upgrades available.

Right now, the sale on Object Desktop is cheaper than doing an upgrade from a stand-alone. Upgrades are not eligible for the sale regardless.

When will there be another sale for object desktop please?
