It has come to my attention that the US Postal Service has drastically raised their rates through the end of the year. I copy their statement below. I don’t have an exact percentage, but one recent order was costing almost double the usual amount. In normal circumstances, when the shipping cost is greater than what is charged, I usually absorb the extra amount. But these new, if temporary, rates are proving to be too much for me to absorb.

In light of this I give you three options:
1 – Wait until after December 27th to place an order.
2 – Place an order and then wait to hear from me what extra shipping is needed. Then decide whether to pay the extra amount or cancel the order and receive a full refund.
3 – Contact me with a list of the items you wish to order, and I can figure the total cost in advance. I will send this total to you in the form of a PayPal Money Request, which you can choose to accept or reject.

I apologize in advance for this, but as you can understand this is beyond my control.
Here is the statement I received from USPS:

On 8/14/20, the United States Postal Service filed notice with the Postal Regulatory Commission (PRC) to increase package prices on commercial shipments for a limited time during the fall and holiday peak season. The planned temporary price adjustments are in response to increased expenses and heightened demand for online shopping package volume due to the coronavirus pandemic and expected holiday ecommerce.

As a result of these changing market conditions, the Postal Service is planning a time-limited price increase on all commercial domestic competitive package volume from Oct. 18 until Dec. 27, 2020. The proposed commercial price increases for Priority Mail Express, Priority Mail, First-Class Package Service (FCPS) and Commercial Parcel Select will take effect Oct. 18 at 12 a.m. Central time and continue until Dec. 27 at 12 a.m. Central time. After that, prices would revert to the previous 2020 prices.
