Hello. I just yesterday purchased your plugin and I would like some
help. Thanks for your time in advance.

I want to implement the following shipping rule

#1 ALL ZIPs (between 00000-99999 and with TOTAL ORDER >=69 has 0 shipping
#2 ZIP between 54000-57999 and with TOTAL ORDER >=20 has 0 shipping
now considering below that we have TOTAL ORDER <69
and ZIP 54000-57999 has TOTAL ORDER <20
#3 ZIP between 54000-57999 with WEIGHT<=3 has 3.30$ per kg and every next kg +0.75
#4 ZIP between 28000-29999 with WEIGHT<=3 has 4.05$ per kg and every next kg +1.23
#5 ZIP 78010 (specific one) with WEIGHT<=3 has 5.26$ per kg and every next kg +1.85
#6 ZIP 72410 (specific one) with WEIGHT<=3 has 5.26$ per kg and every next kg +1.85


actually there around 15 zip ranges (like #3 and #4) with above thinking (3kg and extra 1kg)
and some over 100 specific ZIPS (like #5 #6) with same charge (3kg and extra 1kg)

So how could this be done ? So It will help me to do the rest

Thanks in advance for your time and valuable help

Dear gbrakos,
I would use rules like:
This should give you a good idea how to write the remaining rules.

Regarding the calculation of the shipping costs, e.g. "Shipping=3.30+0.75*ceil(max(Weight-3,0))":
-) 3.30 is the fixed amount
-) Every kg above 3kg is 0.75
-) The nr of kg above 3kg is calculated as: Weight-3. However, for orders below 3kg we have to set this to 0, thus the max(Weight-3, 0). That max call ensures that we don't add anything for orders below 3kg. For orders above 3kg this is the same as Weight-3.
-) The ceil(...) function is needed to round the increment to kg. In particular, a weight of 3.5kg is 0.5kg above 3kg, but it should count as 1 full kg, so we have to round it up to the next full kg.

Of course, you can also write two rules (one for weight<3kg, one for weight>=3kg) instead of trying to combine them to one rule (where the formula is a bit harder to understand). But all you save in the formula is that one max(..., 0) call:
