Shipping Costs
Shipping fees can be a deterrent for buyers, as they might inflate the overall cost of purchasing items, especially for low-priced goods.
Quality Variation
As items are sold by individual sellers, there may be significant variances in item quality, which can lead to buyer dissatisfaction if expectations are not met.
Competitive Market
With numerous listings available for similar items, sellers may find it challenging to stand out and attract buyers amidst stiff competition.
Account Limitations for Sellers
Users can sell only a limited number of items at a time unless they meet certain sales thresholds, which could limit potential revenue for active sellers.
In-app Purchase Challenges
The necessity of in-app purchases for some features might be a barrier for users who prefer fully free platforms.
