Right now, LEGO Shop@Home has two free-with-purchase promotions going on. First up is Jor-El who was last seen back in June and was free with a $75 purchase. Now, buy any DC Super Heroes keychain and he will be automatically added to your cart. The keychains are $4.99 and the keychain lights are $11.99. They combine with the no-minimum free shipping promotion as well so this is a great way to stock up on some stocking stuffers.
Next is Flashback Shredder. He, too, was a promotional giveaway and was free with a $75 purchase back in July. Now, buy any LEGO Teenage Mutant Ninja Turtles set and he will be automatically added to your cart. This combines with the current Black Friday promotions like the no-minimum free shipping and the free holiday set.
Both promotions run until December 31st or while supplies last while the Black Friday promotions end on midnight December 1st.
