Practical guide to running a flash sale on sellX — a timed discount with an end date, the original price struck through on product cards, product pages and WhatsApp share links

Why Flash Sales Work in Egypt

Egyptian buyers love an offer. But a line in your Instagram caption saying "20% off" isn't enough — they need to see the old price and the new price side by side while they're browsing your store.

The problem is that most sellers put the offer in the description text: "was 300, now 200". That's invisible on product cards, and a buyer scrolling fast never sees the deal.

sellX handles this automatically. The moment a sale starts, the original price is crossed out and the sale price appears in a highlight color — on product cards, the product page, and even in the WhatsApp share link. When the sale ends, the price goes back on its own.


Steps: Set Up a Sale in Under a Minute

  1. Open Discounts — tap Create discount, then Amount off products.
  2. Find the product — search it by name and tap Set discount.
  3. Choose the discount — a percentage (20%) or a fixed amount (50 EGP). The preview shows the old price crossed out and the new one.
  4. Choose when it ends — pick the end date and time. Every sale needs one: that's what makes it a flash sale.
  5. Save — the sale starts right away and ends by itself at that time.

That's it. Open your storefront — you'll see the old price struck through and the new price in red, until the end date.

A few things to know:

  • The sale covers every variant. On a product with sizes or colors, the discount comes off each variant's own price (XL at 320 → 256 with 20% off).
  • You can also add it from the product. Open the product: its Sale card sets the same timed discount.
  • A price that's lower for good isn't a sale. If the new price is here to stay, set the product's compare-at price instead — the old price stays crossed out with no end date to manage. See different prices per size or color for how it works.

Why This Actually Converts

Buyers see the savings before the price

When a buyer sees "300 EGP" struck through next to "200 EGP", their brain calculates the difference automatically. That's psychologically stronger than writing "33% off" in a caption.

The offer shows in the WhatsApp share

When you share a product link over WhatsApp, sellX generates a message that includes both prices. The buyer sees the offer before they even open the store.

Stock counter adds urgency

If you set stock to 20 units, the counter drops with every order. When it hits 3, psychological pressure kicks in — "I'd better grab one before it's gone".


Flash Sale Strategies That Work

1. Seasons and holidays

The first week of Ramadan is peak traffic. Prepare the offer the day before, launch it at 4 PM, and run it for 24 hours only.

2. Weekend drop

Thursday evening to Saturday morning is prime shopping time in Egypt. A 20% weekend offer moves slow-moving stock.

3. Monthly cleanup

Last week of the month, pick 5–10 slow movers and apply 30% off. It frees up cash and clears inventory.

4. New-collection launch

When a new collection drops, run 15% off the previous collection on the same day. The old stock funds the new drop.


Pricing Tips That Protect Your Margin

Not everything needs a discount If you have 50 products, pick 10. The offer should feel special, not constant.

The original price must be real Don't inflate an original price to fake a bigger discount. Buyers spot it and you lose trust.

Calculate your margin before dropping the price If your margin is 30% and you discount 20%, you're left with 10%. That's still fine if the sale brings a new customer who'll reorder.

Say when it ends — everywhere The sale stops on its own at the end date you set. Repeat it in your Instagram caption: "Only until Friday" doubles conversions in the final 48 hours.

Use Instagram Stories The moment you launch, post a Story with the struck-through card + a link sticker to the product.


When NOT to Run a Discount

  • Brand new products: Buyers don't know the value yet — selling at full price builds anchoring.
  • If your margin is under 25%: The discount eats the entire profit.
  • Every single week: If buyers learn you run a sale weekly, they'll wait and never pay full price.

How sellX Compares

Most e-commerce tools in Egypt either ask you to type the discount manually in the description, or force you to edit the base price and lose the original. Either way, the buyer doesn't see they're saving.

sellX keeps both prices (original + sale). The original stays visible — struck through — everywhere. Zero extra effort on your side.


The Bottom Line

A successful flash sale = a real discount + visible savings + a deadline.

sellX handles the middle piece for you automatically. You decide the actual discount and the deadline.
