Before getting started, please make sure I can reach you!
The e-mail address in your PayPal user profile is the only way that I can contact you with questions, or in case something goes wrong.
Please make sure PayPal has an up-to-date e-mail address, and that I'm not going into your spam folder.
Update 10-4-2023: Please check your address at PayPal. They recently changed their standards due to changes by the US Post Office.
Useful things to know:
Ordering is via PayPal
HPF-Pre is only available in USA, Canada, and Mexico
All shipments are FOB Madison, Wisconsin
I typically use USPS Ground Advantage (formerly called USPS First Class Mail) with delivery confirmation
USA and Canada orders go out with a prepaid mailing label generated within PayPal
Mexico customers typically contact me with special instructions
USPS tracking information isn't always updated quickly. You may receive your order before the tracking information shows up.
What happens:
When you receive an order confirmation from PayPal, they send me an e-mail with the order information, and your order shows up in my PayPal account summary. So far, I have experienced no errors or problems with PayPal.
This is a part-time home business with a two-weekly work cycle:
Orders received Monday through Friday go into the weekend production queue if possible
I build during weekends
Shipments go out on Monday. Sometimes orders that come in during the weekend take an extra day or two depending on what my family schedule is like
Temporary situation as of 10-4-2023: Two weeks is more realistic.
When I generate your USPS shipping label within PayPal, they send you a shipping notification. My experience with PayPal and USPS have been excellent.
If the buttons don't work, you can also just PayPal me the money. It works the same either way, including your buyer protection. Make sure you say that you're buying merchandise, not sending a gift. I am willing to pay the PayPal fee in order to maintain the Buyer and Seller protections, which I believe are beneficial to you.
Where's my shopping cart?
PayPal opens up a new tab in your browser with your shopping cart.
What if something goes wrong?
Contact me. Among other things, I can cancel your order with no penalty to you or me. Check your e-mail at the e-mail address that you use for logging into PayPal. For some people, this is an address that they rarely look at.
