giffgaff was launched as a no-thrills, super-cheap network. No call centres, tv ads, paper advertising (it was word of mouth only) or shops to run. All those savings were poured into making call and data charges as low as possible... or at least, that's what I thought.
These past few years, the prices have been climbing and so has visible waste - TV ads, quality sim packs (they used to be very cheaply made) and money wasting deals such as this.
