Every Canadian reseller eventually faces the same question: which platform should I focus on? The answer isn't one-size-fits-all — each platform has distinct strengths, weaknesses, fee structures, and buyer profiles. This guide breaks down eBay, Facebook Marketplace, Kijiji, and Whatnot so you can build the right multi-platform strategy for your mystery box reselling business.
Platform Fee Comparison — Your True Net Margin
| Platform | Selling Fee | $40 Sale → Net | $100 Sale → Net |
|---|---|---|---|
| Facebook Marketplace | 0% | $40.00 | $100.00 |
| Kijiji | 0% | $40.00 | $100.00 |
| Whatnot | 8% | $36.80 | $92.00 |
| eBay Canada | 13.25% | $34.70 | $86.75 |
| Poshmark Canada | 20% (over $15) | $32.00 | $80.00 |
Which Platform is Best for Each Item Type?
| Item Category | Best Platform | Why |
|---|---|---|
| Electronics (branded) | eBay Canada | National audience, buyers pay premium for specific models |
| Brand-name footwear | eBay + Facebook | eBay for size-specific national search, Facebook for local quick sales |
| Kitchen appliances | Kijiji / Facebook | Too heavy to ship — local 0-fee pickup is most profitable |
| Lululemon / activewear | Poshmark / eBay | Fashion-focused buyers pay full market value |
| Mixed lots / volume | Whatnot | Clear entire box in a 2-hour show, 8% fee |
| Beauty / skincare lots | Facebook Marketplace | Local buyers buy fast, zero platform fee on bundled lots |
| Collectibles / trading cards | eBay Canada | Only platform with sufficient collector buyer base |
The Multi-Platform Income Stack
The most profitable AmazeDeals resellers don't choose one platform — they use a coordinated multi-platform approach that maximizes revenue per box:
- List high-value singles on eBay (electronics, shoes, branded clothing) for national pricing
- List bulky/household items on Kijiji or Facebook for zero-fee local sales
- Bundle slow-movers into lots on Facebook to clear inventory efficiently
- Clear volume on Whatnot weekly shows for fast turnover with growing loyal buyers
Resellers using all four channels consistently earn 30–50% more per box than those using just one platform, because different items find their optimal buyers on different platforms.
