The serialized item takes longer due to the FFL paperwork.
Welcome to the forums @nyckillz1 
thats a good thing to know though for folks who dont realize that they will process seperate ad ship seperate because one is a serialized item and one is not. im sure you’re post finding out what happened there is goig to help a lot of others who come here asking the same thing.
Welcome to the forums @tenglee4
You will have to contact Sezzle directly to figure out what is going on.
You can try talking to PSA when they open tomorrow but they are not in these forums.
Best of luck.
I’ve already contacted palmetto. It’s not them and it’s Sezzle that’s declining the order. How are others able to order ARs and I cannot with a handgun. This is frustrating.
I got the same problem today, got confirmation from Sezzle then a notice that it was cancelled. Haven’t gotten a reply to my email from PSA. I took was trying to get a handgun.
Welcome to the forums @AZarmsguy
Like can we even finance any weapons with sizzle at all? If not why’d listed as an option for payment.
What did Sezzle say when you contacted them?
@tenglee4
My spending limit is $500 since I signed up for Sezzle in April , maybe the gun is over your limit?
First rep I spoke said certain merchant aren’t allowed in their policies. Assuming that’s right, but how are others posting on this forum purchasing ARs with sezzle. It makes no sense to me. Can buy ARs but cannot buy handguns??
finally found an answer. Thanks bud. EDIT
Same processing error again. The total order was lower than spending power. I am going to try doing this on a laptop after the order gets cancelled. One last try …
Are you trying to buy something that may not be allowed in your state? Don’t know just trying to help @tenglee4
@Jammo isn’t there something about the first payment/down payment about needing to use debt card or bank account? I’ll have to check after work on my desktop.
Yes the payments are tied to a card or checking account for the deductions to be made. Also they do not accept American Express or Capital One cards.
I have no affiliation with Sezzle, I’m only stating what I have read
It’s the PSA 9mm threaded barrel. Also have my CCW that is irrelevant but we’re allowed to have this specific handgun in WI.
Tenglee4, did it work when you did it on the laptop?
No it did not. Same processing error on both my iPhone and on the computer. I just gave up.
