I was able to find and order the part I needed quickly. I appreciated the ability to calculate shipping costs up front.

We apologize for the delay and inconvenience you experienced with your order. Unfortunately, the manufacturer notified us after the order was placed that part of the order had been discontinued, which contributed to the delay. We also understand your cancellation request was not processed in time before one item was shipped. To help resolve the matter, we have offered a return authorization so the shipped item can be returned for a refund. If there is anything else we can do, please let us know.

The experience was excellent,
but I can no longer make purchases because I can't access my account. It was canceled because I'm from Lima, Peru, but I make purchases for delivery in Miami, Florida, USA.
I want to continue working with you by purchasing pH, conductivity, O2, turbidity, and other solutions.
Please let me know how I can continue making purchases without a registered account.

Great products, problematic shipping
I appreciate that Global Test Supply offers reasonably priced, high-quality products, and their customer service representatives were helpful to the extent possible, but was dissatisfied with the shipping process and level of communication provided regarding orders.
My order ran into a number of shipping issues and delays, during which time I did not receive any status updates from GTS. I had to initiate all communications and follow-ups, and issues took a long time to resolve.
It took over a month to resolve an issue with my initial order -- to fix the issue, I was instructed to cancel and resubmit my original order, but the prices of the items I was purchasing had since increased by a total of ~$200. GTS did not honor the original prices I had placed the first order under. After placing the order again, shipping was estimated to be ~1 week. It took another month for the order to arrive due to stocking issues that I was not made aware of until I followed up with GTS.

Good Products, Good Prices, Great Service
Global Test Supply made it easy to find and order what I needed. I recently refurbished a 40-year old Snap-On AC Manifold Gauge set. The old gauges were cracked and leaking oil, and were calibrated for R12. I found an affordable pair of Mastercool 3.5" gauges and protective boots and ordered them online. The checkout and payment process was quick and easy (Paypal), and GTS kept me updated on the progress of the order throughout. I will definitely consider Global Test Supply for my future AC needs.

We sincerely apologize for the delay with your order, Pamela. An unforeseen issue on the manufacturer’s side prevented us from receiving the part within the expected timeframe. We are currently reviewing this with them to ensure that lead times are met moving forward. Thank you for your patience and understanding.
Still not happy
Still not happy. Still did not receive my missing parts to my chimney sweep. Now I'm supposed to send pictures of what I got so you can see what I didn't get after I gave you a detailed inventory and an email of what I did not receive from what I was supposed to receive. Why is this my responsibility? As a customer I feel like I should have had better service. I am in the customer service industry and I never treat my customers this way. Emailed three times called twice. All they said is sent pictures. I don't understand what's sending pictures would do.. Even ask for a complete refund and I would send back the few pieces I didn't get. Still nothing
