What? Tell you not to keep going back! I for one will not tell you that. I say don't walk but keep running and buy it up.
You will find a way to buy it at that price cause later in the year what you find there may be seen in a fabric store somewhere at $5 and up a yard. Wish we had such fortune here. I did however last year get some pretty good deals in good quality fabric at about 50 cents or a dollar bundle and most often it was a couple yards or more in each that I bought.
Just act all excited with your hubby by saying something like "look what I got for $1.99 a yard and this stuff cost $5.99 a yard at ???????. I just saved US $4.00 a yard. That's a savings of $680. for 170 yards of fabric. He'll be happy you just saved HIM $680 in the long run.
