The wording of their message does seem to imply that Toys R Us will still honor any unfulfilled online orders placed before this occurred, but there's been no official word one way or the other on that front, so further confirmation is awaited there.
Check below for the full message, and let us know if this will affect your plans at all by posting in the Energon Pub. As always, stay tuned for more Transformers news, however disappointing it may be.
Thanks for visiting. We have shut down the website for any purchases but our brick and mortar stores are open and holding going out of business sales. You can keep up-to-date with this historic sale at http://goodbuytoysrus.com. We encourage you to stop by your local store and take full advantage of the deep discounts and deals available. Thank you for your business and support over the years.
Sincerely, Toys"R"Us and Babies"R"Us teams.
