Thak God there's We-Supply in San Diego! There is no place like it around here. It's so handy to go there and pick up the supplies for computer and A/V that they carry. They have a good selection of cables, accessories, jacks, and equipment racks. They are the only place in town that has a combination of products that bridge A/V and IT, especially for commercial projects. The staff is knowledgeable and helpful, and the prices are reasonable.
Great place for electronic parts but hard to leave without buying something I didn't really need.
I felt like a kid in a candy store walking in here. I needed header pins for my microcontroller projects, and they had plenty of them just hanging out on the shelf. I'd normally have to order them online and wait for them. So I appreciated that there was a local place where I could find them and take them home earlier. PLENTY of other things as well. Great place, would highly recommend 👍
Seemed helpful when I called around 3 PM on a Friday afternoon to ask about a replacement connector cable Targus laptop charger. I asked if it was ok to come in close to closing, as I would be walking or taking a bus to their location. The person on the phone said "no problem, we're open until 5 P.M. take your time" your price will be $29.99 plus tax" Upon arriving, I explained to the counter service man that an important Gmail and Facebook password were inside my laptop, and that my interest in buying a charger was to regain these passwords with a working charger that would power my laptop while plugged in and help me get to my Desktop. I smiled and explained that I wouldn't ask to return the charger after, as I am not "that kind of customer". I Didn't get a smile or nod of understanding in return, so I presented the $32 cash in good faith and placed it on the counter to relate to the counter helper that I was serious. I explained that my laptop was had physical damage (yet was still in working condition) due to it being held in a old backpack and the fact that I had recently been homeless (which lead to considerable wear and tear to the physical appearance of my laptop, as shown in the attached pictures). However, the way that I was spoken to changed markedly when I mentioned this and when they saw the worn and frayed condition of my laptop. The counter service man told me that my port probably wouldn't work, and another man behind the counter said that it probably wouldn't be a good idea for them to try their product on my laptop due to its condition. I used a moist towel to clean off the debris and asked again if it would be ok to try it. I asked again if it was ok for me to attempt to log into windows, and that I may have to call the person who installed Windows on my laptop (to regain the correct password) --- This seemed to cause friction with the counter help staff, and after it took 4 call attempts for me to reach the person and retain the password, the counter service person told me "your behavior is weird - we've already given you 3 attempts and this product works - and we don't offer any returns or exchanges. This took place within a span of about 17-18 minutes. Another worker came up to the counter and mentioned that since I was "acting weird" that I should consider either buying the charger or leaving. Really not used to this being judged personally - seemingly with my character and intentions called into question - by any place of business I've worked with in my 49 year lifetime; perhaps these men are strong in their trade and deliver good products, but I was struck not only by their impatience and unwillingness to devote just 10 minutes of their time to help me, but also the frowning faces and attitude of "take it or leave it - and you've already taken up a lot of our time here" -- It seemed that as soon as I explained that I had recently been homeless - and upon seeing that my laptop wasn't in the best of condition - that they in effect refusing to do business with me. If any electronics store or repair shop is reading this and is willing to help me, please contact me. Even though I have experienced bouts of homelessness, I have no criminal record or addictions to vices, and only wish to be treated humanely and with respect. I don't feel that the employees of We-Supply (Willy's Electronics) were respectful to me - in fact, I sensed a level of disrespect and disdain towards me. I left the store within 20 minutes of arriving.
