The Jacket Maker's headline offer is 15% off your order, a flat discount that works across the entire range and suits most shoppers looking for immediate savings. Since none of these deals require a voucher code at checkout, you'll simply select your items and the right discount will apply based on what you're buying and which offer gives you the most money back.
For small to medium orders under $200, the 15% off your order deal is your best bet, delivering a straightforward discount that applies to everything. If you're buying men's leather bags specifically, the 25% off men's leather bags offer beats the standard 15% off, so you should head straight to that category and grab what you need there.
When shopping clearance or factory seconds, the flat 40% off factory seconds and clearance sale offer is hard to beat and will save you far more than any other discount on those items. If you're browsing leather bags that are not currently in clearance, the up to 50% off leather bags deal may apply depending on which styles are included, and you should check whether any bags in that category qualify before settling for the 25% men's option.
For orders above $200 where you're buying general stock jackets and apparel (not the specific categories above), compare the 15% off and 12% off offers in your basket, though the 15% off will typically give you more value. If your entire basket is clearance items, the 40% off factory seconds and clearance sale applies and will almost certainly save you more than any percentage off your full order.
Only one offer applies at checkout, so add everything to your basket and check which discount produces the larger saving. The best choice depends on what category you're shopping in and whether any items qualify for a specialized deal like the leather bags or clearance discounts. If nothing special applies, the 15% off your order will work across everything you've picked and provides solid savings on the full total.
