if you're reading this, you've already seen the new version of pos-aid.com. We're pretty pleased with it (but I guess we would be!). One thing we've been asked for is clear pricing so everything is now online and you can even go ahead and arrange your installation! This has all been done in Shopify by someone with relatively little web design experience so hopeful it shows off what Shopify is capable of.
We'd love any feedback you may have of course. Be as honest as you like!
