if you want to express the meaning of 'within two days', you use 'by'. i.e. by 2 days' time

I'll just add that tea and coffee are both extremely common in the UK. There are at least 10 tea rooms within walking distance of my home! That being said, cafes are more common and they serve both coffee and tea. Teapigs is a UK brand. http://www.teapigs.co.uk/ I would consider it an upscale, expensive tea.

While there are plenty of Americans who like tea, I think most prefer coffee. Those who drink both probably drink more coffee. Coffee shops and tea houses are very popular, though again, you're more likely to see a coffee shop that also serves tea than a tea house, which might not serve coffee at all. After two days.

1. I love tea. Yes we drink tea in America and in England. I have not heard of that tea but I will look for it. 2. It means after two days

THANK ALL OF YOU VERY MUCH. O(∩_∩)O
