Comparison Methodology - Real Test Guide

Comparison methodology: Real Test Guide compares Amazon, AliExpress, and 1688 for US buyers by looking beyond the listed price. This comparison methodology explains how we review landed cost, delivery time, return practicality, buyer protection, MOQ, and sourcing friction.

Comparison methodology for Real Test Guide price comparisons — Real Test Guide uses a comparison methodology that separates listed price from practical landed cost and buyer risk.

Comparison methodology overview

Each price comparison starts with a specific product or product type. We try to match pack size, material, dimensions, included accessories, and visible listing details as closely as practical. When listings are not identical, we state the difference and treat the comparison as directional rather than exact.

Amazon price and domestic buying convenience
AliExpress price, shipping terms, seller signals, and buyer protection
1688 listed price, MOQ or tier price, domestic-China assumptions, and US forwarding friction
Pack size, per-unit price, delivery time, return practicality, and purchase risk

Comparison methodology for listed price vs landed cost

A low listed price does not always mean a lower real cost. For US buyers, 1688 prices usually exclude international forwarding, customs handling, domestic China shipping, language friction, and practical return support. AliExpress may include some shipping or buyer protection, while Amazon prices often include domestic fulfillment and easier returns.

When we estimate landed cost, we describe the assumptions in the article: exchange-rate timing, approximate package weight or volume, freight-forwarding range, MOQ, and whether the item is a one-unit purchase or a bulk sourcing case. These estimates are educational, not a freight quote or customs ruling. For official import basics, see the US Customs and Border Protection guide to internet purchases.

Data sources in our comparison methodology

Articles use the screenshots, source URLs, and price rows collected for that specific comparison run. Product prices, coupons, shipping terms, and stock status can change quickly, so each article includes a checked date or data cutoff. Readers should verify the current listing before buying.

1688 notes for US buyers

1688 is a domestic China marketplace. Many listings may allow low MOQ or even single-unit domestic purchase, but that is not the same as a simple US cross-border retail experience. We avoid blanket claims such as “1688 is wholesale only.” Instead, we read the specific listing and explain the added friction for US buyers: payment, forwarding, language, delivery time, and after-sale support.

Editorial judgment

Our recommendation is based on buyer fit, not just the lowest visible number. A single household buyer may reasonably choose Amazon even when AliExpress or 1688 has a lower listed price. Bulk buyers, resellers, or buyers already using a freight forwarder may reach a different conclusion.
