Reply To: Today's grammar lesson

From a dikduk perspective, “only” is quite correct. The author is stating his/her belief that 290 shekels is a low price for the service offered. It implies the parents are getting a good deal. The author may be totally treff when it comes to facts, but from a grammar perspective he’s glatt kosher.

I suggest you look up “misplaced modifier.” Two hundred ninety shekels is a good price, and it deserves an “only.” But to say the only thing parents have to do is pay implies there is nothing else they have to do.
