Stupid question about St Tropez

[UnMasterChef]

I'm thinking about getting a fake tan before my holiday so I don't frighten the fish I've not had one in years. I've looked at two local beauty places, one says it will take 15 mins and cost £25, the other says it will take an hour and cost £55, why the difference? I've no idea why they are so different.

Thanks

Look at what products they use. A spray tan would be 25 min but if they have to rub it will take about 45m.
I find spray tans come off unevenley so I would always go for a "rub" tan!

They both say St Tropez, the cheap one says spray, the other doesn't say, so I'm guessing Rub.

Mind you I've just found the beauty salon at the local college, looking at the prices very tempted to give its whirl
