CFD Multi-Tiered Shipping For WooCommerce Plugin

WordPress administrators can create a multi-tiered flat rate shipping
cost based on the total number of items in a WooCommerce cart. The
store administrator can choose to apply this shipping method to all
available countries or to specific countries.

This flexible shipping method provides up to 4 tiers, suitable for USPS
flat-rate boxes. Also provided are several large-order shipping cost
calculation methods for refining your total shipping costs calculations.

By default there are four tiers; 1, 2, 3, 4 – small to large. Tiers 3
and 4 may be disabled if not needed.

Examples

One of the following examples may help you determine how best to
configure the settings to get the results you require. Once you have
saved your settings, be sure to look at the review table at the bottom
of the settings page to confirm that your settings are calculating the
shipping costs as anticipated.

Example 1

• Default 4-Tier shipping method (all tiers enabled; suitable for USPS flat-rate)
• Base cost: $0.00 (default)
• Large Order Shipping Cost Calculation Method: prorate

 Tier|Max Qty| Cost ----+-------+------ 1 | 2 |$ 5.95 2 | 4 |$12.65 3 | 10 |$15.90 4 | 15 |$17.90 pro| each |$ 1.12 

Results

• Shipping cost for 5 items = $15.90.
• Shipping cost for 12 items = $17.90.
• Shipping cost for 20 items = $17.90 + 5 x $1.12. Total cost is $23.50.

Example 2

• Custom 3-Tier shipping method (tier 4 disabled)
• Base cost: $0.00 (default)
• Large Order Shipping Cost Calculation Method: prorate

 Tier|Max Qty| Cost ----+-------+------ 1 | 10 |$ 7.00 2 | 40 |$21.00 3 | 160 |$42.00 4 | disabled pro| each |$ 2.00 

Results

• Shipping cost for 35 items = $21.00.
• Shipping cost for 120 items = $42.00.
• Prorated shipping cost for 200 items = $42.00 + 40 x $2.00. Total cost is $122.00.

Note

• Disabling tier 3 and enabling tier 4 works results in exactly the same cost calculations.
