Oh Navigon, "Why do you take me so many different ways to the same place????" Is it to show me 'who is boss?' Or is it to provide me a variety in travel adventures?

Last June, the first week that school was out for the summer... my friend Lisa came over, from England, for a week's visit.  I had done an Internet Search for yarn stores around this area and I found the address of a 'outlet' shop for an Italian Yarn company.  *I had posted about this earlier this year.   So, I decided to go back there yesterday to get some winter wool yarn before the yarns changed with the seasons.   Here are my purchases. This is a shawl in one of the ROWAN pattern books.   The skein in the back is a dark grey 100% alpaca.   It is so soft.  I need a better green.  Or at least another green to shade the leaves/stem with. I got this skein to add the center flower colors for some of the flowers.  I thought that way- that I'd have a variety of colors to use in one skein.  I am NOT GOING TO ADD the long curly fringe to the shawl.  I really needed one more skein of the grey- but, they were out of that particular color. I bought 3 different purples to 'consider' for this cardigan.  I have only used the suggested yarn ONE TIME for anything that I have knitted.  I constantly make substitutions for the yarns that I have or that I can purchase.  I did get a brown that looks exactly the same color.   Which purple do you think that I should use?  The one under the yellow?  The one directly under the brown?  Or the last one a blue-purple color? I got this color changing yarn to mix with the solid black (both just happened to be the same thickness!) in a colorwork/fair isle hat/glove set. And, they had some 100% cashmere.   Sigh.   I bought a light grey and a dark grey to do some color work gloves, hat, cowl?  Something along those lines. And, they had this Lion Brand Yarn:  Amazing... at such an AMAZING PRICE that I couldn't pass it up!   It is a wool/acrylic mix.  This is an American yarn brand and sure enough when I looked on the label- it said:  MADE IN ITALY!   All the other yarns are Italian yarn companies.   I'm going to knit one of those super long wide cowls that an loop around your neck twice.   I think that I'll just do a knit/purl ribbing look or maybe a mistake rib?  This is the 3rd or 4th time that I've been to this shop in the year that I moved here.  I didn't find out about it until last spring.   My Navigon system has led me to this place in a different direction each time.   Each time, that I start the system-- I have only been one mile apart from all the other starts.   I think that I have found the best and most direct path this time though.   It was exactly 9.5 miles away!   Not bad at all.   The last time that I went there- right before Christmas to get some Christmas gifts (and a little yarn- not as much as this shopping trip) it was a 15 mile away trip.  I think that I will start going there more often.   The yarn is greatly discounted - even less than the yarn sold in the Italian yarn stores and of course much less than the yarn stores in the states.   WHICH is exactly why I want to purchase certain yarns before I leave this area.
