In honor of Presidents Day, the unofficial name for the Washington’s Birthday holiday that is on Monday, participating Subway restaurants are giving away one free cookie with any purchase per customer.

The free cookies are only available Monday while supplies last, according to Subway’s Facebook page.

To learn more, visit www.facebook.com/subway and click on “events.”

When I request a freebie or sample, I often have to agree to receive a company’s occasional e-mails. Most of them end up getting deleted from my mailbox or I later unsubscribe to them. However, I’ve learned that some lead to even more freebies if I look closely enough.

While in pursuit of a Cheerios sample last year, I signed up to get the Betty Crocker e-mail newsletter. I have to admit I apparently have been glancing through it too quickly because it was only recently that I noticed an offer for a free monthly sample.

This month’s offering, available to the first 10,000 people, is for free au gratin potatoes. Next month is sugar cookie mix. (I’m definitely going to have to watch for that one!)

The rules say you have to be a recipient of the subscriber e-mail in order to be eligible for the samples. It’s too late to join and get the potato sample but if you like sugar cookies, head to www.bettycrocker.com and sign up.

You’ll also get access to a bunch of coupons there. When I last checked, the site had 57 coupons worth $70.88. I printed out nine of them for a savings of $7.19.
