2026-03-12
Shipping costs at OopBuy are directly tied to your parcel's weight. A little preparation can prevent surprise fees at checkout. This guide will help you estimate, calculate, and compare to ship smartly.
Step 1: Estimate Your Total Parcel Weight & Size
Begin by gathering the product details from your cart.
- Product Weight:
- Dimensional Weight:dimensional weight. You'll need the package dimensions (Length x Width x Height). If unsure, estimate by considering the product size.
- Add Packaging:packaging material
Quick Tip:round up your total weight estimate by 0.5 kg
Step 2: Calculate & Compare Cost Per Kilogram (kg)
This is the key to finding the best shipping value. OopBuy often displays shipping options with a total cost. Use this simple formula:
Cost Per Kg = Total Shipping Cost / Total Estimated Weight (kg)
Example: Cost Per Kg = $16 / 3.2 kg = $5 per kg.
Compare this rate across different shipping carriers (e.g., Standard, Express, Economy). A lower cost per kg usually means better value for heavier packages.
