The last design of the second round of seasonal Miku figures, summer, has been revealed:
Additionally AmiAmi is selling the Rin&Len 10th Anniversary Tote Bag and Pass Case (Rin, Len)
Yet, as far as I understood the Can Badges and acrylic stand are only available is you purchase through Cocollabo itself, so I'm still not sure which shop to choose Σ(゜ロ゜;)
I know it's a tiny bit early but thanks to GameStop and Hot Topic, it's time for the usual Black Friday, Cyber Monday and Black Friday early preview week sales thread (did this back over on VO for the past few years). The sales are listed for continental US stores.
The only other Miku thing they sell on there is a cycling Miku Figma (link) so keep an eye out for any other sitewide sales over the next week.
Starting this sunday (Nov 18th) GameStop has a sale on various merch items and board games. You have to buy a bag for $5 and every single merch item you buy that can fit in it gets it's price marked off 30% (you can read the fine details here). The only way you can get a discount on Miku stuff like figurines is if you have a larger than usual GameStop that carries a ton of merch. You can check on their site if they carry those in your nearby store.
Certain supermarkets also have deals on GameStop gift cards like $10 off a $50 card if you buy $50 groceries like my local grocery store does. The important thing to note is that GameStop gift cards also work at sister store ThinkGeek (the same for ThinkGeek cards working at GameStop). The only Miku thing ThinkGeek carries in the webstore is that Miku Keytar bag which happened to be on sale for $20 the past few days Hatsune Miku Keytar Sling Bag
November 19th edit: the ad is out and it has nothing particularly interesting in terms of deals. Sorry.
Barnes & Noble
They sold alot Miku artbooks and manga over the years. They have the usual $10 back when you buy a $50 gift card so there's that I guess. They might put out more details on deals over the next week on their site.
Half Price Books
They're embarrassing Barnes & Noble in the quality of their sales this year. Yes they're doing the discounted gift card thing (get $5 after buying a $25 gift card), but also in store on Black Friday they're offering a 20% off discount on everything along with the first 100 customers receiving a $5 gift card and a tote bag with a random tote including a $100 gift card (details). The chain has a wide selection of Miku artbooks & manga HPB | Search for hatsune miku . Last year a few of their stores offered a deeper discount lower than 20% so try looking for your local store's social media page to see if they going to do that at that particular store.
Pop In A Box
It's a pop vinyl focused store that carries several cryptonloid Funkos (here & here). Their Black Friday page so far is only a tease for the sale so keep an eye on it for now.
Edit: All the vocaloid pops are sold out.
For Fans By Fans, Squishables and Crunchyroll Store
Not sure what they're doing this year but they did some discounts last year. Yet again, keep an eye on their socials.
Haven't been in the crafts retailer in a pretty long time but I do remember that certain stores do carry posters from Trends International. Not sure if they carry any Miku posters. If you do see one over there on Black Friday weekend, here's a few coupon codes you could use Michaels Black Friday Ad Posted!
They have some deals too this month with their own dedicated launch page Black Friday Sale
November 20th update: GameStop's frontpage (under 'Collectables & Offers') mentioned their webstore is offering 30% off all merch purchases over $100 discount. That means the bridal Miku figure you can preorder from them for $319.99 would be marked down to $223.99 with this deal. For purchases made during this time over $35 will also get free shipping too. When thanksgiving begins, they're just be offering a general 25% off figurine discount instead GameStop Black Friday 2018 Adscan - Page 11
Well, that was fast. Nendoroid 1039, Miku Symphony, is already up to pre-order!
Although she doesn't come with much she's defenitely pretty.
The costumes for this year are super nice, I hope they consider doing some more nendos of the Symphony theme. I would love to own a full set ala Hanairogoromo~ Nendoroid Hatsune Miku: Symphony 2018-2019 Ver.
