Don't click on the links....Its just taken me 10 mins to stop the flash up of links... Not sure if you are aware of the problem CG..Maybe why no replies.!
To answer your question...not to sure what your question is...I wouldn't say its a scam on price, different places charge RRP, Below RRP and over RRP. The bikes are different bikes and tbh personal taste.
Like anything, you can buy a 3 wheeler car or a top of the range merc.
I would get whatever is within your price range and that your ds likes.
DD was 4 last month and we got her a bike, from toys r us and was disney princes. She loves it.
Not sure where it is in the range but know its the height we wanted and was what dd wanted.
