If you're shopping for Diane Castel perfumes this week, you're in luck. We've scanned every store on TajPrice to find the products with the biggest price differences between sellers. The result? You can save up to 40.7% just by choosing the right store. This update covers June 21–28, 2026, and focuses on the Private Collection and a few other gems where the spread is highest.
Let's start with the king of savings: 
Black Addiction Private Collection by Diane Castel for Unisex - Eau De Parfum, 50 ml. This bold, modern unisex Eau de Parfum has a price range of 24,880 IQD to 35,000 IQD – a massive 40.7% difference. That's over 10,000 IQD you could keep in your pocket.
Next up, four fragrances with an identical 36.7% spread: 
Grey Private Collection by Diane Castel for Unisex - Eau de Parfum Intense (woody-smoky unisex), 
Eastern Sand Private Collection by Diane Castel for Unisex - Eau De Parfum, 50 ml (oriental spicy), 
Silver Sky Private Collection by Diane Castel for Unisex Eau de Parfum (crystal-clear woody mist), and 
Fève Exquise Collection Privée by Diane Castel for Unisex - Eau De Parfum, 50 ml (sweet tonka-coffee-vanilla). All four are available from 24,880 IQD up to 34,000 IQD. Same bottle, big savings.
Two more Private Collection scents also hit the 36.7% mark: 
Cristal Rouge Collection Privée by Diane Castel for Unisex - Eau de Parfum, 50 ml (spicy-floral-vanilla) and 
Ayesha Collection Privée by Diane Castel for Unisex - Eau De Parfum, 50 ml (floral-woody-oriental). Both start at 24,880 IQD and go to 34,000 IQD.
Don't overlook the larger bottles either. 
Bleu Barbade by Diane Castel for Unisex - Eau De Parfum, 100 ml – a fresh citrus-floral-woody cologne for all – ranges from 39,900 to 50,000 IQD (25.3% spread). That's a potential saving of 10,100 IQD.
On the lower end, 
Ivory Powder by Diane Castel for Women - Eau de Parfum, 100 ml (4.0% spread) and 
Prodigio by Diane Castel for Men - Eau de Parfum, 100 ml (1.9% spread) have very tight price differences, so you won't find huge savings there – but they're still great scents at fair prices.
Our advice: for the best deals this week, head straight to the Private Collection 50ml bottles and Bleu Barbade 100ml. Compare stores on TajPrice before you buy, and save big.
