Transformers fans and bargain hunters got lucky on Sunday April 5 and Monday April 6. That’s when you could get either (or both) of the above Transformers Animated Play Set 2-packs for 80% off—or $4.99.

Yep, that’s right. A brand new toy, exclusive to Target and only in the store for less than 1 month at 80% off.

Evidently this had to be a goof. There’s no way they would sell these at that price, intentionally anyway. Using the nice “Find It At A Target Store” link, I located a nearby store that showed them in-stock and at lunch a buddy and I drove on down.

I picked up the last one of each set—they’ll make great presents. But I can say, they were priced at $4.99 and they were sold out.

Rumors are flying today that the price has been adjusted to $22.99, but I’ve not been able to confirm that. The site still shows them at $4.99.

My guess, they were supposed to be discounted by $4.99. Most of the other Transformers product is currently 20% off. An computer glitch or human error  accidentally reversed the numbers and a lot of people got lucky.

Just the other day, Carter decided he wanted a Transformers birthday party. This came as quite a surprise, since he’s been saying for months that he wanted a Fantastic Four birthday party, because “I’m turning 4.”

Jill and I absolutely couldn’t come up with a good Fantastic Four cake idea, but Transformers we can do. I remembered seeing the above Optimus Prime cake a few weeks back on Digg and I knew that we could easily adapt it to look like the Optimus from the movie.

Even better, the person that built the Optimus cake documented the whole process, which should save us a little trouble.

Now that’s a movie I want to go see (480p HD Trailer Link).

After a few boring trailers, they finally deliver on the good stuff and I think this preview shows plenty of what the public needs to see, big robots transforming and fighting each other.

Unlike the sequels that dominate the summer (Spider-Man 3, Pirates 3, Shrek 3, Fantastic Four 2), the Transformers are making their first appearance on the big screen. They’re an unknown to a large audience and that audience wants to have an idea of what they’re going to get for their $8 movie ticket. Heck, I grew up watching Transformer and it wasn’t until this trailer that I actually got excited (just watch Optimus transform and tell me you don’t grin when you hear “the sound”).

That’s not to say I don’t have complaints. When the guy at the end says “Bring It!” it makes me want to cringe. But another part of me cracks up at Shia LaBeouf’s line “It’s a big robot, it must be from Japan.” I’ll go in expecting Independence Day and perhaps I won’t be disappointed. How hard can it be to mess up giant robots that transform and beating each other up?
