A business letter worth admiring

There are a few things in this letter I would correct: deeply-valued shouldn't have a hyphen; the men's names should have probably appeared in the same order throughout; and the family may be close, but there does need to be a space in "TheOrton." All in all, though, I thought the letter was wonderful. The message was warm and sincere, despite the sentimental content, and the picture of the company that emerged was solid.

I was especially happy to see that

• the right case (objective) was used in "No matter whom you're shopping for this holiday season";
• parallelism was preserved in "you'll find truly unusual gifts that evoke happy days, promote warm feelings, and bring a beaming smile to the face";
• a hyphen was used in the adjectival compound "a family-owned business";
• no comma separated adjectives in "special young person";
• no comma appeared before the restrictive clause "when young ones raced downstairs"; and
  
• that was used to denote the restrictive in "a family and a tradition that have endured."

The diction of the letter is also deserving of mention, I think: cherished; authentic; precepts of ardent, honest customer service; gratitude for…kindness, privileges, and opportunities. And note that three sentences toward the end begin with we:

• We will celebrate being part of a family and a tradition that have endured through hard work, frugality, imagination, and ingenuity. [The last four nouns are nothing special by themselves, but together they are fresh and strong.]
• We will celebrate the vast and growing audience of customers who today are part of that tradition, expanding it through their own deeply-valued stories and memories.
• We are delighted to welcome you to this tradition and to our family.
  

When the reader finally gets to "Enjoy!" the exclamation point does seem fitting.

Hyphenated compound

Because I wondered what other compounds would be treated like "most recent edition" (in Exercise F), I checked the Chicago Manual of Style Online (16th edition) and found that this compound comes under the rule for adverb not ending in ly + participle or adjective.

The guideline is:

Hyphenate before but not after a noun; compounds with more, most, less, least, and very usually open unless ambiguity threatens.

Examples:

a much-needed addition

it was much needed

little-understood rules

a too-easy answer

the best-known author

a lesser-paid colleague

the most efficient method

a less prolific artist

a more thorough exam

the most skilled workers (most in number)

but

the most-skilled workers (most in skill)

One word or two words?

What is the difference between using "every day" and "everyday"; "can not" and "cannot"; "never mind" and "nevermind"; "alright" and "all right"; and so on?
