A '70% Off!' banner is exciting, but is it the best deal? Understanding the nuances of sales is crucial for maximizing your savings. Let's break it down. Percentage-off discounts (e.g., 20% off) are most effective on higher-priced items. A 20% discount on a ₹5000 item saves you ₹1000, while the same discount on a ₹500 item saves you only ₹100. Conversely, dollar-off discounts (e.g., ₹500 off) are often better for lower-priced goods. A ₹500 discount on a ₹1500 purchase is a 33% savings, which is more significant. Another common promotion is 'Buy One, Get One' (BOGO). This is only a good deal if you genuinely need two of the item or if the 'free' item is something you would have purchased anyway. Also, pay attention to 'tiered' discounts, like 'save ₹1000 on orders over ₹5000.' These encourage larger purchases, so ensure you're not overspending just to hit a threshold. The ultimate goal is to evaluate the final price. A simple 30% off from a site like 99 Online Shop, with no minimums or complex tiers, often provides the most straightforward and significant value for your money.
