Costco

"If you raise the effing hot dog, I will kill you. Figure it out."

Costco Wholesale Corporation is a membership-only retail warehouse club based in the United States, specializing in bulk sales and large items.

Over the years, Costco has carried a few exclusive Transformers toys, in addition to the regular mass retail releases. Their exclusives are usually of the "large multi-pack of unchanged toys" variety, but occasionally they have gotten truly unique items. Not so much anymore though. Either way, these items are typically sold at prices way below normal retail prices at other outlets.

Costco exclusive toys

Energon

Overload & Optimus

Costco's first exclusive, for the Energon series, was... a lot. Both in terms of sheer mass and deco tone. This set is easily Costco's most distinctive exclusive, as from here on out, it's pretty much all just minor changes or straight re-packs.

Cybertron

Very slightly different from other versions

The Cybertron Magnus/Optimus multi-pack is a weird one. The Ultra Magnus is a straight re-packaging of a Robots in Disguise Magnus redeco offered by Sam's Club a few years prior, while the accompanying Optimus Prime is a redeco of that Sam's Club set's Optimus, but with the yellow turned back to red, making it look a lot like the original toy, but it kept the Sam's paint colors, making it just a bit different.

The Optimus/Wing Saber set, meanwhile, is a straight repackaging of normal retail releases, just with a bonus DVD.

Transformers (2007)

The live action movie toyline exclusives were pretty much just straight repackages. But sold much cheaper.

Universe (2008)

Here we have Cybertron product repackaged for 2008 Universe line, but hey, they're cheap if you missed them the first time around.

Revenge of the Fallen

More unchanged toys for the Revenge of the Fallen release.

Transformers (2010)

Exclusive redecoes came back after quite an absence in the 2010 Transformers line, with two shiny versions of Bumblebee in a single set.

Dark of the Moon

This Dark of the Moon set was only available in Canadian Costco stores. It also contains an exclusive "CYBER METAL Armour" redeco of Shockwave.

Kre-O

Costco's Kre-O offerings are just two of the larger first-year sets basically shrink-wrapped together into multipack form.

The Last Knight

Product for The Last Knight was certainly different: a multi-pack of 1:32-scale die-cast metal vehicles from Jada Toys... but they're identical to the individual retail releases.

Bumblebee

Here's where it gets weird! For Bumblebee, Costco offered an 1:12-scaleexclusive radio-controlled racer of Volkswagen Beetle done up offroad-buggy-style.
