I have received about 10 trees from them, avocado and loquat. They generally arrive quickly and in good shape. However, I did receive an avocado in my last order that arrived looking a little rough. The leaves were stressed, the plant generally not vigorous. I replanted in my plant ICU and it just continued to decline, dropping the leaves it had. I contacted Top Tropicals by email and I think the longest reply I got was six words. I sent pictures, hoped for advice. No dice.
The sad part is that I could likely save this plant without them, but would have appreciated their guidance and advice. I work with dozens of different tree species. Customer service could have been much better. The trees are hardly free, so I would be reluctant to order from them going forward.
