Reply To: How to centered the Price Table ?

The pricing table was originally designed for 4 tables, so if you only need 3, then you could adjust the width of them all so it stretches to each end.

Look on line 726 in your css and change the width to around 33% or so until you get the width you want –

.plan-col, 
.plan-col-popular {
    width: 33%;
}
