When ZentBuy looks better
ZentBuy’s sampled shipping was lower on all three routes. If your order is mostly freight, such as low-priced but heavy items, that can outweigh its higher exchange-rate markup.
When KakoBuy looks better
KakoBuy’s exchange-rate markup was 2.5 percentage points lower, which matters more as item value rises. Its longer storage also helps if you collect items slowly, and its domain dates from 2024, compared with June 2026 for ZentBuy.
