Argos eBay (or Argay, for short) has the Virgin Mobile Samsung SGH-C300 for £8.99. Not a bad deal for a decent little slider phone. To top it off, delivery is completely free. Nice.
The phone is a few years old now, and it’s incredibly basic, but it’d do as a starter or back-up handset.
Check out the full specs on the Samsung website.
Argos eBay has a policy whereby you can only buy one phone per month.
