Tips for This Route
- Protect shipments from desert heat. The I-10 corridor through West Texas and Arizona sees extreme temperatures from May through September. Insulated packaging and faster shipping reduce heat exposure for temperature-sensitive items.
- Watch dimensional weight on large parcels. UPS and FedEx use DIM weight pricing, which calculates cost based on package volume rather than actual weight when DIM weight is higher. Right-size your boxes to avoid overpaying.
- Consider USPS flat-rate boxes for heavy items. The Medium Flat Rate Box at ~$16.10 and Large Flat Rate Box at ~$22.45 ignore weight, saving money on dense shipments to San Diego.
- Ship to a staffed location when possible. San Diego’s dense urban areas can create delivery access challenges. Shipping to a UPS Store, FedEx Office, or USPS post office ensures reliable receipt and reduces missed-delivery attempts.
