What version of the rMBP do you have? If it is the 2012 or early 2013 versions you can replace the SSD. Check out http://www.macsales.com/ for upgrade options. If you have a late 2013 or mid 2014 I think you only option is to but an Apple SSD off of ebay or some other parts website. I don't think there are any third party PCIe SSDs out there for those models yet.
 
Latest version .. I know I need the ssd blade like the Mac pro .. I know where to get the drive just wondering about doing the actual swap
 
The swap is simple. The SSD is held into place by 1 torx screw which is accessible by removing the bottom panel.
 
If it's the latest, that means you still have a warranty! Just wondering if you'll be waiting until it expires or you don't care?
 
The last time I looked no one made an SSD for the newest rMBP. I replaced the SSD several times in my 2010 C2D MBA, similar technology, but NOT the same SSD. Mechanically I am sure it's very similar as far as the physical replacement.

You can get them on ebay from people who pulled them from their Macs

I forgot about that. I got my first 256 as a system pull. It mostly was a good drive. ;)
As far as a replacement, the 512 Transcend Jet was an amazing drive. That was my second replacement on my old MBA. Great product.
