Key points

  • ▸ Stacked promotions: "30% off, plus an extra 20% with code" is 44% off, not 50%. The second discount applies to the already-reduced price.
  • ▸ BOGO (buy one get one free): that is 50% off, not 100% off. You still have to want two of the item.
  • ▸ Clearance vs seasonal: 75% off clearance may be a real bargain; 40% off a new-season item is usually the normal markup coming down.
  • ▸ Subscription intro offers: "first month 50% off" on a $30 plan saves $15 once. Compare total 12-month cost, not headline percent.
  • ▸ Tax and shipping kill slim discounts: 10% off a $50 item saves $5, but $7 shipping wipes that out and more.

Examples

  • Black Friday stack
    Laptop "30% off" at $700 from $1,000, plus 10% extra with code. Final: 1000 x 0.7 x 0.9 = 630. Total discount: 37%, not 40%.
  • BOGO math
    Shirts $40 each, buy one get one free. Two shirts for $40 = $20 each = 50% off per shirt. Worth it only if you want two.
  • Subscription tease
    Streaming service: $5/month for 3 months, then $18/month. Over a year: 3x5 + 9x18 = 15 + 162 = $177. Not the $60 the headline suggests.
  • Shipping kill
    $25 item 20% off = $20. $6.50 shipping = $26.50 total. You paid more than the listed price.

Frequently asked questions

› Is clearance always a good deal? Trust & accuracy

Usually, if the retailer genuinely wants inventory gone. Watch for "clearance" that is really MSRP — compare against competitor prices.

› How do I compare two discounts on different items? How-to

Convert each to dollar savings per unit of what you actually want. Percentages are misleading across different base prices.

› How should I use this guide with a Kefiw tool? How-to

Use the guide as the plan and the linked Kefiw tool as the check. Read the steps first, try the move manually, then use the tool to compare outputs, catch edge cases, and decide whether the result actually fits your task.

› What mistake do tool guides help avoid? Troubleshooting

Tool guides help avoid using a utility mechanically without understanding what you are trying to accomplish. Most word, writing, and text utilities are fast, but speed can hide context mistakes. Know whether you are solving a puzzle, cleaning copy, drafting a line, or checking a rule.

› Can a tool guide help me learn the skill? How-to

A tool guide can help you learn if you pause before accepting the output and ask why it worked. Compare your first guess with the tool result, look for the rule or pattern, and repeat that review. Passive copying solves one task; active review builds the skill.
