Going in and saying “Excuse me, but I believe you have made a mistake, at least with regards to the four skeins that were priced at $8.75” is hardly causing a feud. Someone being your customer doesn’t give them license to rip you off.
This sort of “I’ll neglect to adjust the invoice” stuff goes on all the time, unfortunately, and you are perfectly justified in calling them on it… politely.
I’m making knitted floor rugs. I’m on my third one, and the yarn (with shipping) costs about $32 for four skeins. I have at least four more I want to make.
Knitting…it’s an addiction, especially with pretty soft yarn.
And one could easily argue that that isn’t the price of really good yarn–really good yarn can easily cost more than that.
Trust me, Jeff, expensive yarn is an end in itself, whether it one day turns into a sweater (or socks) or not.
Cheap sock yarn is $4.99 a skein and takes two skeins to knit two socks. One can easily go well over $20 for a skein–which should allow one to actually knit two socks, but still. . .
It’s like asking “Why would you make a beautiful cherry dresser by hand and spend all of that money and time when you could buy a dresser for $50 at Wal-Mart?” If you have to ask, just continue to buy mass produced stuff and be happy. Save your money
As to the OP, it could have been an automatically generated invoice or who knows what- your sister should just call the shop and ask about it. I don’t think it was an intentional rip off.
