I don't have real-time pricing data for Pakistan. To find current Game Boy Advance prices:
Local online marketplaces: OLX Pakistan, Daraz.pk, PriceOye, Shophive, Telemart.
Physical retro game shops: Visit electronics markets in major cities (Karachi: Saddar, Bolton Market; Lahore: Hall Road, Hafeez Center; Islamabad: Blue Area, G-9 Markaz).
Facebook Marketplace / Groups: Search "Game Boy Advance Pakistan" or "Retro Gaming Pakistan."
Specialized importers: Some Pakistani retailers import graded/refurbished units.
Price Drivers
Model: Original GBA (horizontal) vs. GBA SP (clamshell, frontlit/backlit) vs. Game Boy Micro — SP backlit (AGS-101) commands highest premium.
Condition: Mint/boxed > working with scratches > "for parts."
Mods: IPS screen mods, rechargeable battery mods, shell swaps — add value if professionally done.
Compare multiple listings before buying. Haggle in person; use COD for online.
