Bulk Sourcing Strategy for E-Commerce Retail

1. Start with a Small Batch Order

市場の反応をテストするのに最適
Helps evaluate supplier reliability
Allows for customer feedback before scaling

S-SHAPER offers low MOQs starting at just 50 pieces, making it ideal for new brand launches or trial collections.

2. Use Tiered Pricing to Your Advantage

Most seamless underwear suppliers offer volume-based discounts.

101～500	$2.20–$2.80
501～1,000	$1.80–$2.20
1,001+	1.50ドル～1.90ドル

Always ask for a price break chart when negotiating with suppliers.

3. Consolidate Orders

Bundle multiple SKUs (e.g., seamless thongs, briefs, and boyshorts) into one bulk order to:

Reduce per-unit cost
Save on shipping
Improve supplier relationship

4. Plan for Shipping & Duties

Options for international e-commerce sellers:

航空速達（DHL、FedEx）	最適	Avg. Time
高速（3〜7日）	Small orders, urgent launches	5～7日

This transparency helps prevent budget overruns and ensures a smoother importing experience.
