Half-price drinks and slushes all day

Ordering through the official app applies the Happy Hour price outside the 2–4 PM window. No code needed.

IN-APP Ongoing

What the offer includes

Placeholder content. Half-price drinks and slushes all day is listed here under the app only category with the code IN-APP. The finished page should spell out exactly what the offer covers: which items qualify, whether sizes are restricted, whether it applies to combos or only à la carte orders, and whether the discount is a fixed amount, a percentage or a free item with purchase. Readers arrive from search expecting a clear answer in the first paragraph, so lead with the discount and the qualifying purchase.

How to redeem the code

Placeholder content. Most offers of this kind are applied inside the official mobile app rather than at the stall, which means the code is added to the order before checkout instead of read out over the intercom. Walk through the steps here: open the app, select the location, add the qualifying item, apply IN-APP at checkout and confirm the discount appears on the total before paying. Note what to do when the code fails, since expired and region-locked offers are the most common reason a discount does not apply.

Terms worth checking

Placeholder content. Offer terms change without notice and vary by franchise, so this section should record the restrictions that matter: one use per account, participating locations only, no stacking with other discounts, and the expiry date listed on the offer at the time of writing (Ongoing). Because this site is an independent reference and does not issue codes, the safest phrasing tells readers to confirm the offer inside the official app before ordering.

Stacking with Happy Hour and the value menu

Placeholder content. The largest savings usually come from combining a promotional offer with pricing that is already discounted: Happy Hour between 2 PM and 4 PM halves drinks and slushes, and the value menu holds a set of items at a fixed low price all day. Explain here whether IN-APP can be combined with either of those, and give a worked example of a full order with the total before and after the discount so readers can see the actual saving in dollars.

What it saves you in practice

Placeholder content. A worked example belongs here: take a typical order, list each item at the price published on this site, then show the total with the offer applied. Being concrete about the saving — a dollar figure rather than a percentage — is what makes a promo page useful, and it also gives readers a way to sanity-check the offer at the window. Keep the example current, and note the date the calculation was last refreshed.

When this offer changes

Placeholder content. Promotional offers rotate frequently, often weekly, and regional franchises run their own campaigns alongside national ones. This section should tell readers how often the page is reviewed, what to do if the code has stopped working, and where to look for the current replacement. Linking back to the promo codes index and to the app keeps readers moving rather than bouncing when an offer has expired.
