Shia LaBeouf's Vegas Wedding

Shia LaBeouf's surprise Vegas wedding Monday with Mia Goth was no free love affair -- but it only set the actor back a few hundred bones.

Obviously, Shia's got the dough to spend wayyyy more ... but looks like he opted for the $700 Elvis Blue Hawaii package, which includes:

- Elvis officiant (with 3 serenades)
- 1 hula dancer
- 6 rose bouquet for Mia, matching boutonniere for Shia
- 10 candid ceremony prints
- Courtesy round-trip limo service from any hotel on the strip or downtown

Not exactly the royal treatment -- especially for an A-lister -- but if you're in the market, the Viva Las Vegas chapel offers just about everything a la carte. For instance, the hula dancer's $100 ... or the pink caddy WITH fog machine will run ya $175.

Take your savings and invest in real estate -- just a tip.
