I am still not a fan of the asphalt conditions at Dollar Tree in San Ysidro (ie unmarked parking…read morestalls and potholes all over). Even when it was 99cent store, the parking area was unpleasant looking.
The inside of the store, on the other hand, was much better looking and maintained. Spacious, clean, organized, mostly stocked items, and wide aisles. Not bad. Also, place wasn't crowded.
There was one cashier with a line of four people. I did my share in waiting in line. Other than this, my shopping experience at this location was fine.
