Those prices were temporary low when we paused the group buy offers during July month, now that the GB are back, many products will have much better pricing than the regular ones in the price list, and the prices you see now in the regular pricing is just the previous ones in June.
You might be frustrated because you will be paying tirz 40mg $530 us domestic instead of the temporary discounted pricing tha twas $390, but it's already the cheapest you will find, you can check all the other vendors if you want. You won't find any other vendor offering tirz 40mg at cheaper than $530 us domestic, and it's $500 international.
