PolyBuys is the student marketplace built for Cal Poly, San Luis Obispo. Every user is verified with a Cal Poly email, so you always know you're dealing with a real student on campus.
Buy and sell textbooks, event tickets, dorm furniture, electronics, clothing, and anything else students need. Browse listings, message sellers directly, and close deals — all within a single app designed around how students actually trade.
What makes PolyBuys different:
• Verified students only - sign in with your Cal Poly email to join a trusted, campus-only community
• Built for speed - post a listing with photos, set your price, and publish in under a minute
• Direct messaging - chat with buyers and sellers without sharing your phone number or social media
• Save listings - bookmark items you're interested in and come back to them later
• Report and block - flag suspicious content and keep the marketplace safe for everyone
No ads. No processing fees. No strangers from the internet. Just Mustangs buying and selling to each other.
Built by Cal Poly students, for Cal Poly students.
