More Yarn to the Rescue, or Should I Just Return?

Searching for the right color of turquoise, and to keep myself from losing my connection with creativity by not giving in to resistance, I will be up to my eyeballs in various shades of different yarns if I don't get results, soon.  That first order was more green than blue.  This second stab is more blue than green.  When will it end?

Could it be this computer monitor that's throwing me off?  Okay, so I will admit, again, that I don't want to visit the local yarn shop to browse in person because I hate the clerks there.  They are so nasty I don't understand how they stay in business.  Why are yarn shop proprietors so nasty?  You would think they'd be happy to have knitters or crocheters come through the door at all, and be smiley and helpful!  No, not here.  They scowl a half-hearted hello as a greeting and look down their nose at you if you ask questions about their uber-expensive yarn.  Not a fun experience by any means, so I avoid them at all costs.

Shopping online is faster, cheaper and you don't have to deal with yarn snobs.  All the info is right there: gauge, yarn content, needle size, washing instructions, yardage. The only things you cannot do is feel it, smell it, or see it with the naked eye.  Oh yes, smell is a factor with wool, it could stink!  Yes you want the yarn to have a certain tactile quality depending on the item of your project.  And the color could be crucial, or not. Returns are usually easy and may cost the price of shipping and I can deal with that. At the local shop they only offer exchanges for returns, not cash back.  But how much is the price of nastiness? No thanks!

The first yarn order of greener turquoise was not the gauge I needed for the project, but I love it so I'm keeping it for something else.  It's a superwash wool yarn which means it can go in the washing machine, but it may have to air dry.  That means a longer drying time.  Problem or not?  The second order of bluer turquoise has everything I want in a washable and dry-able yarn, but the color might be off and as I tried making a swatch for gauge it was sticking on my needles.  Is that a problem with pima cotton or just me?  I have questions.  Return or keep?

Should I bite the bullet, cover my eyes, hold my nose, be brave, throw myself in the lion's den by going to the nearby yarn shop and asking my questions?  I'm shaking just thinking about it.
