Charles Tyrwhitt is running an "Up to 70% Off Men's Shirts" sale as the main deal on the page, which is best if you can buy marked down sale shirts because savings on sale styles can reach as much as 70% while stock lasts. If the shirts you want are not on the sale, the site’s automatic multi buy discounts, buy 2 for 10% off, buy 3 for 15% off, or buy 4 for 20% off, are the straightforward options to use.
For large shirt buys (four or more shirts): Add four shirts to your cart and the 20% off when you buy 4 shirts deal applies automatically, so this is usually the best choice for a four item shirt order. For example, on a $200 order of four shirts, the 20% discount reduces the total to $160, saving $40. Offer used: 20% Off When You Buy 4 Shirts.
For three shirts: The automatic 15% off when you buy 3 shirts will trigger at checkout. For a $150 three shirt order, 15% off brings the total to $127.50, a saving of $22.50. Offer used: Buy 3 Shirts, Get 15% Off.
For two shirts: Any two shirts will pick up the 10% off when you buy 2 shirts offer that is applied automatically. On a $100 two shirt order, 10% off reduces the total to $90, saving $10. If the two shirts are custom styles, the 10% off when you buy 2 custom shirts applies instead but works the same way. Offer used: Buy 2 Shirts, Get 10% Off or 10% Off When You Buy 2 Custom Shirts.
For one shirt or small purchases: If the shirt you want is marked as a sale style, the Up to 70% Off Men's Shirts sale may offer the biggest saving, for example a shirt marked down from $80 to $24 at 70% off saves $56. If the single shirt is not on sale, there is no site wide promo code live, so you will pay full price. Offer used: Up to 70% Off Men's Shirts for sale items; otherwise no automatic discount.
For first time shoppers or low spenders: Signing up for the newsletter is available and may deliver future promotions, but it is not an instant discount and is not the page lead. Use the automatic multi buy discounts for immediate savings.

When choosing, calculate the final cart total with the automatic 10%, 15% or 20% discounts and compare that with the price of any sale marked items in your cart. Take whichever option leaves you with the lower total; these automatic offers apply at checkout and you do not need a promo code.
