Oklahoma City packs three dated crowds into the 2027 spring. The city's marathon weekend is April 23 to 25, 2027, the Festival of the Arts fills Bicentennial Park from April 22 to 25, 2027, and the NCAA Women's College World Series opens on Thursday, June 3, 2027 at Devon Park, with a championship series on June 9, 10 and June 11, the last marked with an asterisk in the NCAA's table. A store that sells caps, tees, prints or gifts can match one of those weeks with a small, dated offer, and a State Fair that runs Sept. 16 to 26, 2027 gives the year a fall tail. The city's own tax page lists a local rate of 4.125 percent and a combined 8.625 percent, with 8.975 percent in Canadian County and 8.75 percent in Cleveland County. This page sets out the dates, the rates and a buy X, get Y plan for each window.
Choose one window and one pairing, such as a shirt and a cap or a print and a card. The Festival of the Arts is listed for April 22 to 25, 2027 and the marathon weekend for April 23 to 25, 2027, so the two overlap, and a store that tries both needs separate pairings and separate banners.

Start on the first day the organizer lists and end on the last. For the marathon weekend that is April 23 to 25, 2027, and the organizer's page does not name a race day, so do not write one in the banner. Add the free item's landed cost, not its retail price, to your margin check and cap the number of gifts to the stock you hold.

Open the offer on Thursday, June 3, 2027 and end it on Thursday, June 10, 2027. The NCAA's table marks June 11 with an asterisk and the page does not explain it, so check the table again in May and ask the NCAA before you include that date.

Place test orders to addresses in the Oklahoma County, Canadian County and Cleveland County parts of the city and read each tax line. The city's page lists 8.625, 8.975 and 8.75 percent combined, and the city's own local rate is 4.125 percent of that.

Keep the same pairing for the State Fair if it fits your product, and end it with the fair on Sept. 26. Compare units sold in each window with the weeks around it, and keep the log so next spring's dates are easy to set.
Build it with the Buy X, get Y template.
The marathon's site gives a three-day weekend, April 23 to 25, 2027, and not a race day. A store that sells running gear or apparel can start a buy a shirt, get a headband offer on Friday, April 23 and end it on Sunday, April 25. Keep the copy respectful, because the race's name refers to a memorial, and do not use the race's name or logo as your own.

The Festival of the Arts is listed for April 22 to 25, 2027 in Bicentennial Park. A seller of prints, cards or frames can pair a print with a small card or a mat at no charge above a spend level, and say the festival is a separate event, not a partner of the store.

In 2027 the series opens on Thursday, June 3 and runs through a championship series that the NCAA's table lists for June 9, 10 and 11, the last marked with an asterisk that the table does not explain. Plan the offer for June 3 to 10 and ask the NCAA what the asterisk means before you promise anything for the 11th. Use generic words such as team shirt and cap, and leave out the NCAA's marks.

Oklahoma City has three dated events from April to June 2027, so a store can choose the week that fits its product and run one short offer with a clear start and end instead of a long sale.
The Oklahoma City Memorial Marathon's site lists the 2027 race weekend as April 23 to 25, 2027 and, in the pages we read, does not say which day is race day.

The same city page gives 8.625 percent as the appropriate combined sales tax for an Oklahoma City purchase, or 8.975 percent in Canadian County or 8.75 percent in Cleveland County, so the total can depend on which county the delivery address is in.
