I don't know if this is what you want. But this is what I do.
Type thundercracker and toysrus in chrome, then you will have this page:
https://www.toysrus.ca/en/Transforme.../D0CAF3BB.html
Then this is where thing gets interesting. Type the skn number in search column, you won't find anything
Below is another example, type cyclonus and toysrus in chrome will lead you to this page
https://www.toysrus.ca/en/Transforme.../14A0C9C9.html
However, when you type the skn number in toysrus search column, you will get...
https://www.toysrus.ca/en/Transforme.../24BDC877.html
Rhinox XD
Either I have a misunderstanding about how it works, or the whole toysrus database is a mess
I really appreciate if anyone can explain what is going on?
P.S
oops sorry, I overlook it. you want ss thundercracker. Still I would say try to put the name in chrome and see will it work. Many times they have the page, but you can't find it in toysrus search option
