No problem.
Recently, I ordered from both SRY (for their US warehouse) and Nexaph (which only ships from the US). Both shipped immediately, with SRY by USPS ground advantage and Nexaph by UPS Ground (which arrived two days sooner for my location). Both kits arrived in good condition, with Nexaph having better labeling on the box/kit, including a QR code about the testing.
For SRY, I ordered using e-mail since they don't have a website like Nexaph does. For SRY, I payed using Ali pay (using my credit card), which has a surcharge, but it's worth it for a greater level of traceability/accountability than crypto. For Nexaph, I payed directly by credit card.
