I won't be updating my review for the iShop2Go and planning to do review for GK Gundam because they are basically run by same owners or person. All the Gunpla pricing should remain the same including the shipping even they move all their existing products there.
To be honest, I am really disappointed about them as a customer. Not only they didn't inform us they could get limited Gunpla from P-Bandai and selling resin kits. Instead, they kept quiet and create more complicated ways, such as making it's existing customers to open another account and had to purchase some products that were not found at iShop2go separately at the sister site secretly for years. What worst that its existing customers are paying more on unreasonable extra shipping cost separately.
Yes, I knew about the sister site from last year when I first visit after someone told where to get the P-Bandai Gunpla. It's easy to find out about it because the price and promotion gave it away the hints also the top ten product review video posted at the site. I do feel bad not mentioning in my blog but speculating without proof might get me into trouble. So I rather wait and see. Since the owner personally went public announced at their front page, I still felt they gave a bad impressions hiding the sister site identity.
There is no doubt that so far they are the only Gunpla shop I know that still offering a good price for Chinese Hobby magazines with limited kits online from Hong Kong. Nonetheless, it is advisable to be careful and do more survey on the pricing because there are now many products that sold more expensive for some reason.
