I want to use your plugin but my requirement are as below , so let me know if it is possible 1499 Per month – member gets 5kg/week ( 20 kg a month ) to purchase and 2199 Per month – member gets 10 kg/week ( 40 KG a Month ) to purchase
if member purchase 3 kg in a week – 2 kg get forwarded to next week but not added to next month as its expire ( Membership will only for one month )
Membership will be created only by Admin – no frontend things
Secondly, it is possible to limit customer purchases based on weight. Generally, what you are asking is possible. However, the only issue I see is your time limits and carrying forward. The limits can only be set for one period i.e. either by month or by week but not both. In your case, I would recommend using monthly limits instead of weekly.
Here is an example of the limits that would be possible:
1499 Per month – member gets 20 kg a month to purchase and 2199 Per month – member gets 40 KG a Month to purchase
1499 Per month – member gets 5kg/week to purchase and 2199 Per month – member gets 10 kg/week to purchase
Either of these is possible but not both at the same time. Also the limits cannot be carried forward.
