Start with the selected line
LitBuy’s shopping guide relates the estimate to parcel weight, shipping method and destination, and the final freight to packed weight and size. Before comparing two amounts, record the same destination, line and currency. Ask which measurements and additional charges the quote uses.
| Record or ask | Why it matters |
|---|---|
| Line and destination | A rate from another route is not a like-for-like comparison. |
| Packed scale weight | Use the parcel with its packaging, rather than adding product-only weights. |
| Outside length, width and height | Record the units and the final package dimensions. |
| Weight rule and divisor, if applicable | Do not assume every line uses the same formula. |
| Rounding, minimums and added charges | An unrounded calculation alone is not a payable quote. |
Separate scale weight from space
Actual weight is the packed parcel’s scale reading. Volumetric weight converts its dimensions into a weight for charging purposes. DHL’s published explanation compares the two and uses the greater value. Check your selected LitBuy line’s own rule; DHL’s divisor below is an example, not a universal platform formula.
Scale weight: 2.0 kg
40 × 30 × 20 ÷ 5,000
= 4.8 kg
With this example rule, compare 2.0 kg with 4.8 kg before rounding and other charges.
Work through the example
The illustrated box occupies 24,000 cubic centimetres: 40 × 30 × 20. Dividing by 5,000 gives 4.8 kg, greater than the hypothetical 2.0 kg scale reading. Under that example rule, 4.8 kg is the higher starting value before any applicable rounding or other charges. This calculation does not produce a shipping price.
Compare packing choices with protection
If a parcel could safely fit into a 40 × 30 × 15 cm box, the same example divisor would give 3.6 kg. That arithmetic does not show that your items can be compressed safely, that the option is available, or that the bill will fall. Ask about the following tradeoffs before changing the packaging.
| Possible choice | What to compare |
|---|---|
| Keep an original box | Is it needed for protection, storage or the item’s intended use? |
| Remove an original box | What outer protection replaces it, and what are the finished dimensions? |
| Compression or vacuum packing | Could pressure or creasing affect the item, and is there a service charge? |
| Combine items | Compare the complete quote, packing requirements and line limits rather than only a price per kilogram. |
Keep an estimate-to-final record
Save a dated estimate and compare it with the finished-parcel record. Keep unknown values marked as unknown. Do not silently enter zero for a charge that has not been quoted.
| Field | Estimated record | Final record |
|---|---|---|
| Date and parcel contents | Save the estimate date and selected items | Record the final date and confirm the same contents |
| Line / destination / currency | Copy from the estimate | Confirm the same comparison basis |
| Packed scale weight | Estimated value, if shown | Measured value, if supplied |
| Outside dimensions | Estimated dimensions, if shown | Final length × width × height |
| Chargeable weight | Rule and value used | Rule and value used |
| Packing and service options | Record requested options and quoted fees | Check the options and fees actually applied |
| Discounts, if any | Record the deduction actually shown | Confirm the final deduction without assuming eligibility |
| Freight and added charges | Itemized quote; unknowns left open | Itemized final amount |
If the amount changes
Check the comparison basis first, then the measurements, packaging and charge breakdown. A smaller scale reading alone does not establish that the total must fall: first check the line’s charging rule, final dimensions and itemized charges. If the difference is still unclear, ask support which entry changed and keep the explanation with the quote. This guide does not predict a refund destination, coupon entitlement or guaranteed saving.
Please compare the estimate dated [date] with the final quote for parcel [reference]. Please confirm the packed weight, outside dimensions, charging rule and chargeable weight used for each amount. Which freight, packing, service or discount entry changed? Please provide an itemized explanation before I proceed.
