I honestly don’t know what my next purchase will be. It depends on how you want to define a few things.
Right now, I’m in the typical “client late with the check” pattern. If I get the check, one of the first things I’m doing is settling up with a store for two items they are holding for me, then they’ll ship all the stuff I’ve previously paid for, plus those two items, plus a hard drive, since I’m doing a video transfer for the guy. It wont’ arrive in time for Nationals. I’m not concerned.
The next, if I can swing it(if that check arrives), I’ve got a used Gelada in mint condition I’m gonna spring for. No way this will arrive in time for Nationals.
At Nationals, I gotta clear up a purchase with a vendor there, plus get some new goodies. That my be the next purchase. There was an inventory glitch, so an item I wanted was not actually in stock, so I have a credit at the moment, which has been reduced by tossing an item into that order. So, I still have credit, so I’ll use that towards one item, plus I may purchase a few other items. I actually requested the initial order to be held in the first place as I new a new item was coming so why make 2 shipments? With the unexpected change, I decided “hey, you know, I really don’t need any of this right this second anyways, so could I just pick it up at Nationals?” and the answer was “you bet”.
Concentrating on stuff I want to get at Nationals only:
General Yo Prestige, B-grade only. Maybe 2 if I can afford it. I think my boy deserves a General Yo, although oddly enough, those are ones in my case he never touches.
Clear Rally. 2 if I can, one for me, one for my kid. His first One Drop.(If I can, I’m gonna see about getting him a Gnarwal for Christmas)
If I can afford to do so:
C3 Speedaholic, 1 of each color, but 2 in blue, as one is for my kid. He chose blue. If I’m short on funds, I’ll just get my kid a blue one for the time being.
Duncan Strix would be lowest on my priority list for Nationals. I mean, I could just wait it out and get it at YYE later on.
If YYE has a booth, I’m stopping by. Not sure if I’m getting anything, I don’t want to play politics, but hey, if the price is right and I have cash, who knows…
Most of my other wants are more “common” items, so nothing I need to worry about getting “right this second”. Anything else are new items not yet released or in production, or items that have not shipped yet to retailers for resale.
So, I have stuff queued to be paid off, a BST to finish, a credit to use up, and then flat out purchases. I’m not trying to complicate things.
That feature sold the yo-yo. 
There are a ton of videos on Youtube if you do a search. I’ve seen people dampen the hat bill, then squeeze it around a bottle with a rubberband around it to hold it there, and let it sit overnight. :-\
