I need to buy synergy caps and a 10 ball bearing. The problem is no store sells both. (Sorry for talking about other stores.) I found Yoyoguy, but how good/reliable is it’s shipping?
Its shipping is reliable. I’ve always had great service with them.
And you don’t need to bump something within 30 minutes 
Oops. How quick is it?
Same as YYE IMO
www.yoyoz.co.uk have both in stock
Well they all ship through USPS (duh). It all comes down to the time between order and shipping. There’s normally not a big difference from stores here, not more than two days… usually.
Addment: Last time I ordered from the guy, it took about one week (including weekend). FAST.
Yes, yoyoguy is great. Last time I ordered from them, it took 5 days I think, including the weekend, so they’re very realiable and fast.
