It ' s basically a marketplace of couponsgood deals for services , events , and tangible goods . Make sure to look at the reviews , the fine print , and ask yourself do I really need this ? Not everything is a good deal even if it seems like it is . Also , it ' s a good idea to research the business separately from the Groupon listing and look at original prices . Download the app and mess around with it for a week or so before you purchase a deal . When you purchase for the first time on a new account you can get an additional 25 % off with a promo code . Promo codes come around during holidays , too . I ' ve had a good experience so far . <| sep |> It ' s not that crucial . First 5 weeks of my cycle was Tues 9 pm and Sat 9 am , had to pin early on Tues during 6 th week so switched to 6 pm and Sat 6 am , was late from work during 8 th week so switched to Tues 7 pm and Sat 7 am and I felt great . Obviously TRY and be as consistent as possible , but since teste is such a long ester it really doesn ' t make a difference if you switch it up by a few hours . However I can ' t say the same for short esters although this doesn ' t apply to you since I ' ve never tried anything else . EDIT Only ever used teste .
