Please review the below information from David in our U.K Internet Team:

"I've requested a quote for the same branch, dates, times and vehicle group in Internet Explorer, Firefox and Google Chrome and all three gave me the same quote.

I'd suggest that possibly the difference could be down to one of the following causes;

- The customer was logged in with an express card in one browser but not the other
- The yield settings changed between the customer checking in a different browser but the original price was maintained in the original browsers cache memory resulting in the 'old' price still being shown
- The customer selected slightly different dates or times between the two browsers
- A/B testing may have resulted in the user being shown a Prepaid price as default in one browser and a Flexi tariff price in the other browser

Any of these reasons may have been the cause of the problem, but as this is a stand alone case I think we can narrow it down to an issue on the users local machine."
